Riding an ATV or quad means mud, bumps, and ruts that can shake your phone off the bars, blind you with glare, or leave your batteries dead by lunch. The real question isn’t if you need accessories — it’s which ones actually hold up after a hundred miles of trail rattle without draining your budget or your patience.
I’m Min Islam — the founder and writer behind Trending Car. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you ride a Polaris RZR, a Can-Am Maverick, or a simple four-wheeler, the right atv quad accessories turn a rough day on the trail into a controlled, comfortable, and fun experience — and this guide walks you through the gear that actually delivers.
Our Picks at a Glance
How To Choose The Best ATV Quad Accessories
Most ATV accessories look good in the box but fail when the trail gets rocky. Before you buy, check three things: it fits your specific machine’s roll cage or handlebar diameter (most mounts fit 1.75 to 2 inches), it carries a real waterproof rating (IP66 or at least a water-resistant fabric), and the mounting system uses metal brackets or lock-on clamps — not just plastic zip ties. A cheap accessory that doesn’t stay put is worse than no accessory at all.
Fit First: Measure Your Machine
The single biggest mistake buyers make is assuming “universal fit” means any ATV. A turn-signal kit built for 220-inch wheelbases will work on most machines, but a phone mount that only clamps a 1.75-inch bar won’t touch a thicker roll cage. Always check the mount-opening size — 1.75–2 inches is the common range for UTVs and most quads — and measure your bar’s diameter before ordering.
Weather Sealing: The Real Difference
Your ATV lives outside. A cover that says “waterproof” but lacks ventilated panels will trap moisture underneath, causing rust and mildew. A 600D fabric with a PVC backing — like the CAT cover uses — is the balance for breathability plus rain protection. For electronic accessories (sound bars, phone mounts), look for an IP66 rating, which keeps out both dust and powerful water jets from hoses or rain.
Mounting Security: Where Most Accessories Fail
Bouncing down a rutted trail will twist or snap a cheap plastic bracket in a few rides. The best mounts use aluminum alloy or reinforced steel brackets, lock-on clamps that grip the bar without sliding, and at least four contact points. A phone mount with eight claws (like one of our picks below) secures the phone from all sides — not just the corners — so a sudden jolt doesn’t launch it.

In‑Depth Reviews
1. KEMIMOTO UTV Turn Signal Kit with 110D Horn
Our pick — 4.5★ from 986 verified ratings; the strongest balance of quality and price.
A plug-and-play blinker and horn kit that makes your ATV street-legal without cutting a single wire.
This kit gives you four amber LED turn signals and a 110DB horn — the horn stops as soon as you release the button, so no endless honking. The wire harness is color-coded at every connection, and the manufacturer says it fits vehicles up to 220 inches long. That means even a long 6-seater side-by-side has enough cable to reach front and rear. Buyers who installed it on a Polaris RZR and a Can-Am Maverick X3 both reported a 1–2 hour install with basic wiring skills.
Unlike many universal kits that need cutting and splicing, this one uses a labeled relay and a rocker switch that fits standard dash slots. One reviewer noted “the switches fit like a glove in the slots provided in my dash” on a 2026 Ranger 1000. The polycarbonate lens is amber, which cuts through fog and rain better than clear lenses — so drivers behind you see your signal sooner. It is a complete way to add street-legal readiness to machines like the Polaris RZR, Can-Am X3, Kawasaki Teryx, or even a golf cart — no expensive dealer visit needed.
The main trade-off is wire management: the harness leaves extra slack, and you’ll need zip ties (included) to bundle it cleanly so nothing snags on a branch. One reviewer wired it to the accessory side of the ignition so the signals only work when the key is on — a small extra step but worth doing.
Street-ready safety: A complete LED turn-signal and horn package that installs in about an hour — built for riders who need to legally ride from trail to pavement without a separate dealer kit.
Reach for this if: you want a genuine plug-and-play harness that works on Polaris, Can-Am, Kawasaki, and most UTVs — and you need amber signals that stay bright in rain and fog.
Look elsewhere if: you want a license-plate holder included (this kit omits it) or you need a zero-wiring-splice solution for a machine with a non-standard dash switch opening.
2. Ehaho 25 Inch UTV Sound Bar, IP66 Bluetooth ATV SoundBar with RGB Lighting
A 500W sound bar that punches clear audio over engine and wind noise — and survives a mud bath.
This 25-inch bar uses two tweeters, two mid-woofers, and two passive radiators driven by a built-in Class-D amplifier rated at 500W — loud enough to hear clearly over engine noise and wind, even with a helmet on. Bluetooth 5.0 gives a stable 33-foot range from your phone, and a USB port and a 3.5 mm AUX input add wired options. The kit includes two cigarette-lighter power cords at 91 and 130 inches, plus a socket. The IP66 waterproof rating means the speaker housing is dust-tight and withstands powerful water jets — so mud spray or a hose-down won’t short it out.
The RGB lights wrap around the speaker units and both ends, syncing to the music beat. One reviewer called the lighting a “fun bonus” that turns evening trail rides into a social event. Mounting brackets fit any 1–2 inch roll cage, covering Polaris RZR, Can-Am Maverick, golf carts, and boats. Detachable side cables keep wiring tidy: you connect only what you need, no dangling cords. That said, one buyer mentioned “absolutely no bass” — the passive radiators deliver punchy mid-bass but not deep sub-bass, so if booming low-end is your priority, this bar may feel thin. The startup voice chime is also loud; the company support can provide a firmware fix to quiet it.
What stands out
- 500W Class-D amp with separate tweeters, woofers, and passive radiators — clear sound at speed
- IP66 waterproof + dust-resistant housing for mud, rain, and trail debris
- RGB lights sync to music with wrap-around glow on both ends
What to know
- Minimal deep sub-bass — more mid-bass punch than thumping low-end
- Startup voice chime is loud (company support can provide a firmware fix to quiet it)
Your trail DJ: This sound bar is for riders who want loud, clear music that survives rain and mud — with RGB lights for a fun nighttime vibe.
skip it if: deep bass is non-negotiable — the passive radiators don’t produce heavy low frequencies, so audiophiles and bass lovers should look at a dedicated subwoofer system.
3. KEMIMOTO Upgraded ATV Storage Bags, 55L Rear Seat Bag with Built-In Frame and Removable Cushion
A 55-liter rear bag that holds a weekend’s worth of gear and can double as a child’s seat.
The bag measures 33.07 inches long, 17.3 inches wide, and 9.05 inches tall, with a built-in frame that keeps its shape when loaded. Three internal detachable shelves let you organize tools, clothes, or cooler items separately. The top cushion is designed for a passenger up to 5 kg (about 11 lbs) — enough for a small child, though one owner reported an adult leaning back can bend the frame tubes. Seven adjustable attachment straps wrap around the ATV’s rear rack or seat area for a universal fit on Polaris Sportsman, Honda Rancher, Foreman, Grizzly, and similar machines. At 2.54 kg, the bag feels solid but not overly heavy.
The YKK hidden zippers are protected by a fabric cover — a big upgrade from bags where zippers rust or clog with mud. Reviewers praise the material quality for the price, though sticky zippers after dirty rides and the frame’s weight limit on bumpy roads are common notes. Two grab handles on each side make it easy to lift the bag on and off the ATV. Unlike the bulky KEMIMOTO turn-signal kit, this storage bag focuses on practical carry — reflective strips on the seams help trailing riders see you in low light. The honest trade-off: the frame isn’t rugged enough for an adult passenger on rough trails, but as a gear-only bag, it holds a full weekend’s worth of camping supplies.
Gear hauler with a perch: A 55L water-resistant bag with internal shelves, grab handles, and a removable cushion — best for carrying cargo plus a light passenger (child or gear) on moderate trails.
Best for: riders who carry a lot of gear and occasionally need a quick passenger seat for a small child — the frame holds up to 5 kg on the cushion.
Not for: adult passengers or heavy cargo over rough terrain — the frame tubes can bend under adult weight, and zippers need cleaning after muddy rides.
4. CAT MudShield ATV Cover Waterproof Heavy Duty — XXL 102″L
A heavy XXL cover that stops rain and snow without trapping moisture that causes rust.
At 102 inches long, 48 inches wide, and 44 inches tall, this cover fits larger four-wheelers like the Polaris 800 Sportsman and the Honda Rancher 350 with room to spare — buyers report it even covers the tires completely. The fabric is a polyester/PVC blend that is waterproof yet breathable: ventilated panels let trapped moisture escape so you don’t get mold or mildew underneath. An elastic hem plus two adjustable buckle straps keep the cover from flapping in high winds, and reinforced seams add durability at stress points.
One customer observed: “Durable: no rips, tears, or loose threads after over a year.” Another said the wind has “zero effect” when installed on a Polaris 800 Sportsman. The included compact storage bag makes it easy to stow behind a seat or in a toolbox when not in use. The only common knock is that some buyers wish the material were a touch heavier — though most agree it is thick enough for year-round outdoor storage in rain, snow, and dust. If you store your ATV outside, this cover delivers CAT-tough protection at a price that undercuts most premium branded covers.
All-weather armor: A 102-inch waterproof cover with breathable panels and secure straps — built for outdoor ATV storage in rain, snow, UV, and dust.
Reach for this if: you park your ATV outside year-round and want a waterproof, breathable cover that resists tears and wind — especially on larger machines.
Look elsewhere if: you need a cover for a small youth quad or want ultra-heavy-duty 900-denier fabric — this is mid-weight but proven durable for the price.
5. ODI X-Treme Lock-On ATV Hand Grips — Black/Red Clamps
A lock-on grip that uses a mechanical clamp — not glue — so it never spins on the bar.
At just 3.68 ounces and 130mm long, these grips use ODI’s patented Lock-On system: a rigid inner sleeve clamps directly to the handlebar, while the outer rubber sleeve rotates on a bearing for throttle control. The tacky diamond-plate pad pattern gives your gloves something to bite into, even when wet. Because the grip locks onto the bar mechanically, there is zero chance of it spinning during a hard pull — unlike standard slip-on grips that require glue or wire to stay put.
One user highlighted: “Put them on handlebars I decided to replace.. no problem. Took them off and remounted them on new bars. Look great, feel great, work great.” The small 3/4 flange on the inner end keeps your hand from sliding off the bar during aggressive riding, and the rubber compound stays tacky in both hot and cold weather. The 130mm length fits most standard ATV handlebars without trimming. The only thing to note is that these are full-diameter grips — if you run aftermarket thin bars, check that the clamp fits your bar’s outer diameter. This is the upgrade every ATV rider should make — it outlasts most stock grips by several seasons.
Slip-proof precision: Patented lock-on mechanism with diamond-plate rubber — 100% slip-free, no glue, and easy to swap between bars.
Best for: any ATV rider tired of grips that spin or wear out — these lock on tight, feel great, and survive years of riding.
Skip if: you have extra-thin handlebars and aren’t sure the clamp fits — measure your bar diameter before buying to avoid a return.
6. MZS ATV Mirrors with CNC Handlebar Mount — Hawk-Eye Convex
A handlebar mirror that gives you a wider rear view without blurring at speed — and costs less than a tank of gas.
The MZS mirrors use a convex glass lens (clear white glass, not cheap plastic) for a wider field of view — so you spot vehicles and obstacles behind you earlier than a flat mirror would show. The housing is ABS (a hard plastic) injection-molded with a steel stem, and a ball-joint mount allows 360-degree adjustment to any angle. At 2.05 pounds per pair, they are sturdy enough to stay put on rough terrain but not so heavy they bounce on the handlebars. One shopper added “good level of adjustability… didn’t vibrate much” — a common concern with budget mirrors.
The installation is straightforward: clamp the CNC-machined mount onto your handlebars (fits most dirt bikes, ATVs, snowmobiles, scooters, and mopeds) and tighten the bolts. No drilling or modification needed. The “hawk-eye” convex shape means objects are slightly smaller in the reflection — that is normal for a wide-angle mirror — but you see a broader lane behind you. The honest catch: after about three months, one reviewer noted that the mirror joints lost their tightness and started to droop. For the price, these are a solid upgrade over having no mirrors at all — just keep an Allen wrench handy if you need to re-tighten the pivot points occasionally.
What works
- Convex HD glass gives a wider rear view than flat plastic mirrors
- 360° ball-joint adjustment — find the perfect angle in seconds
- Universal clamp mounts on most handlebars without modifications
What to watch
- Pivot joints can loosen after a few months of vibration — may need periodic re-tightening
- Convex lenses show objects slightly smaller than life — takes a short adjustment period
Best for: riders who want a quick, affordable rear-view mirror (convex glass, 360° adjustment) for safer trail riding — especially on a budget.
Not for: riders who need rugged, long-term durability on extremely rough terrain — the joint may loosen over time and need re-tightening every few months.
7. ZIDIYORUO Anti-Shake UTV Phone Mount with Vibration Dampener
The phone mount that absorbs trail vibration to protect your phone’s camera and keep your map steady.
This mount’s defining feature is a built-in vibration dampener — a small rubber or spring-based element that isolates the phone from handlebar buzz. That matters because sustained high-frequency vibration can damage a modern phone’s optical image stabilization (OIS) system — the tiny gyroscope that steadies the camera lens. The aluminum alloy bracket clamps onto roll cages between 1.75 and 2 inches (common on Polaris RZR, Can-Am X3, and Polaris Ranger). Eight claws grip the phone from all sides, holding handsets from 4.7 up to 7.1 inches (0.9-inch max thickness) — including the latest iPhone 17 series and Galaxy S24 Ultra. At just 1 pound, it adds minimal weight to the bars.
One buyer shared a real-world testimonial: “I recently spent a week riding the Hatfield and McCoy trails in WV using ONx Off-road trail maps on my IPhone without a single issue.” The mount rotates 360 degrees, so you can switch between portrait and landscape views with one hand. Unlike the ODI grips (product 5), which solve a different problem (hand comfort), this mount solves a durability problem: keeping your expensive smartphone safe on the trail. The only minor friction point is the six-step installation — it is not hard, but you’ll need a hex key (included) and about 10 minutes to get it snug.
Shake-proof navigation: A vibration-dampening, 8-claw phone mount for roll cages — holds 4.7″–7.1″ phones securely and protects camera components from trail buzz.
Reach for this if: you rely on your phone for GPS trail maps and want to protect its camera from vibration damage — the dampener and 8-claw grip keep it safe.
Look elsewhere if: you never use a phone on your ATV or ride only smooth pavement — the dampener adds value mostly on rough off-road terrain.
Understanding the Specs
Lock-On System vs Slip-On Grips
A lock-on grip uses a rigid inner sleeve that clamps to the handlebar with a pinch bolt — no glue, no wire, no air-gun needed. The outer rubber sleeve rotates on a bearing, which eliminates the spinning that slip-on grips develop over time. ODI’s patented system is the gold standard here, and the 130mm length fits most ATV bars. If you ride aggressively or in wet conditions, lock-on grips are a one-time upgrade that outlasts three pairs of slip-ons.
IP66 Waterproof Rating for Electronics
IP66 means the device is completely dust-tight (the “6”) and protected against powerful water jets from any direction (the second “6”). For an ATV sound bar, that means it survives mud spray, rain, and even a hose-down after a muddy ride. Compare this to IPX4 (splash-resistant only) which would fail quickly on a trail machine. The Ehaho sound bar’s IP66 rating is a genuine differentiator — most budget sound bars are IPX5 or lower and may short out in a downpour.
