That shudder through the steering wheel at a stoplight, the “clunk” when you shift from park to drive—both are classic signs your 2008 Altima’s motor mounts (the rubber-and-metal blocks that hold the engine in place) are worn out. The right replacement set brings back the quiet, smooth idle your car had when it was new. The key is matching the 2.5L engine’s weight and torque with a mount that uses the right rubber hardness (called durometer, a measure of how firm the rubber is) and solid metal construction.
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.
There are four strong contenders that fit the 2007-2017 Altima 2.5L automatic, but they differ in vibration control, material quality, and complete-kit value — read on to see which 2008 nissan altima motor mount best fits your car and budget.
Our Picks at a Glance
How To Choose The Best 2008 Nissan Altima Motor Mount
Your Altima’s 2.5L engine relies on a handful of rubber-and-metal blocks to hold everything in place and soak up vibration. When they sag or crack, the engine shifts under load, sending shakes into the cabin and putting extra stress on the transmission (the gearbox that sends power to the wheels). Here are the three things that separate a mount that lasts from one that needs replacing again next year.
Complete 4-Piece Kits vs. Single Mounts
It is tempting to just swap the mount that looks broken, but the others are often close behind. A four-piece kit replaces the front, rear, and side supports at once, which restores balanced engine support and stops you from chasing new rattles a few months later. Buyers report that doing the full set is the most cost-effective way to get that “like new” feel back.
Material Blend: Metal vs. Rubber Quality
The best mounts use a mix of iron or steel for the bracket and precisely-tuned rubber for the damping element. The rubber’s hardness — called durometer — matters: too soft and it wears out fast, too hard and it transmits vibration rather than absorbing it. Look for mounts from brands that specify stress-testing for extreme temperatures and road salt, which is a sign they take durability seriously.
Fitment for your Specific Year and Transmission
The 2008 Altima uses a 2.5L four-cylinder engine mated to an automatic transmission (it shifts gears for you). All the mounts in this list are labeled for 2007-2017 Altima 2.5L automatic, but a few buyers mention that one mount in a kit did not have a place on their specific car. Double-check your vehicle via Amazon’s PartFinder or confirm that the reference numbers match your originals (common ones are A4339, A4340, A4350, and A4353).

In‑Depth Reviews
1. iKer Engine Motor Mount Set
Our pick — over 4.5★ from 450+ verified ratings; the strongest balance of quality and price.
Iron brackets and 471 ratings make this the most-trusted mount set on the list for exact fit.
iKer’s set is the crowd favorite — 471 ratings and a nearly perfect 4.7-star average, with reviewers repeatedly calling out the exact fit and sturdy material. The mounts use iron brackets and rubber inserts to fix the engine to the body frame, which keeps the 2.5L positioned correctly while eliminating part of the engine’s natural resonance (the vibration frequencies the engine creates as it runs). The main replacement numbers cover A4350, A4353, A4340, and A4339, so it lines up with the most common 2008 Altima mount positions. One buyer specifically mentioned replacing mounts on a 2007 Altima and said “this main mount is better quality than previous Doorman.” Another noted that the rattling coming from the passenger side stopped after a simple install.
At 4.96 kilograms and 14 x 10 x 7.8 inches, it is the largest box in the comparison — a 2.3x size gap over the Loongrie set’s compact 6 x 6 x 2-inch package. While the iron-and-rubber build gives it a sturdy feel, a few reviewers simply said “works good” without mentioning any long-term durability test. It is note the set is not described as a full 4-piece kit the way the YEOPGYEON is. If you want a complete refresh, confirm exactly how many pieces arrive before buying. Compared to the YEOPGYEON, you get more customer reviews for confidence but less guaranteed coverage.
Strong Points
- Highest rating count (471) and a 4.7-star average — real buyers trust it
- Iron construction with a polished finish for long service life
- Multiple buyers confirm exact fit and elimination of passenger-side rattling
- Covers the widest range of OE replacement numbers
Keep in Mind
- Not explicitly labeled as a 4-piece kit — verify contents before buying
- Package dimensions are large (14 x 10 x 7.8 inches), which is bulkier than alternatives
Grab it if: you want the confidence that comes from the most-reviewed mount set on the market, and you trust a brand with hundreds of positive fitment checks from Altima owners. This is the highest-confidence pick for a direct swap.
skip it if: you insist on a guaranteed four-piece kit and want a smaller, easier-to-handle box.
2. YEOPGYEON 4-Piece Engine Motor Mount Set
This set kills steering wheel shake at red lights by swapping every worn mount at once.
You stop chasing one vibration after another with the YEOPGYEON Set because it replaces all four supports in one go. The brand engineered each mount with a specific durometer (rubber hardness) matched to the 2.5L engine’s weight and torque, so it absorbs road noise without wearing out too fast. The 12-pound kit is noticeably heavier than the 4.96-kilogram iKer set, which reflects the sturdy rubber construction. Owners mention that this set resolves the rattling and clunking on the 2008 Altima — one reviewer noted that the original mounts lasted 125,000 miles and said: “if these last half as long, I’m satisfied.” That same owner pointed out that the original torque and lower mounts were visibly broken, and after installing this set the gradual vibration was gone. The kit is also designed to be lab-tested for extreme engine temperatures and road salt exposure, according to the manufacturer.
Front passenger side mounts are fairly easy to install in about 45 minutes, but the rear mount can be trickier to reach without a lift and may require some patience. You get more complete coverage with this set than you would with the iKer set, which is not explicitly labeled a full 4-piece kit.
Why It Works
- Complete 4-piece kit eliminates guesswork; replaces all worn mounts at once
- Durometer-matched rubber tuned specifically for the 2.5L engine’s weight
- Designed to be lab-tested for extreme engine temperatures and road salt exposure
- Customers note it resolves steering wheel vibration and reverse-gear “thunk”
Real-World Catch
- Rear mount installation is more difficult and may require a jack or lift
- One buyer mentioned a mount in the kit did not have a dedicated spot on their specific car
Reach for this if: you want a complete system overhaul that stops cabin vibration and clunking, and you are comfortable with a moderately challenging rear-mount installation. This is the pick for owners who prefer doing the job once with a full 4-piece set rather than a partial swap.
Look elsewhere if: you only need to replace one specific mount and want a smaller, simpler install.
3. Loongrie Engine Motor Mount Compatible with 2007-2017 Altima 2.5L
A powder-coated 4-piece set that resists rust and fits in a box the size of a shoebox.
Loongrie says it uses “the highest quality raw materials” and tests products in an advanced laboratory to meet or surpass OE (original equipment, like the Nissan factory part) quality. The set fits the 2007-2017 Altima 2.5L automatic and replaces the same A4340, A4353, A4350, and A4339 reference numbers as the other kits here. The powder-coated finish on the metal brackets gives it a clean, corrosion-resistant look that the unfinished ENA set does not offer. At 6 x 6 x 2 inches, the Loongrie box is dramatically smaller than the iKer’s 14 x 10 x 7.8-inch package, even though the weight is nearly identical (4.94 kilograms versus 4.96 kilograms).
Reviewers point out that the mounts eliminated engine vibration and fit perfectly — one reviewer called it “for like OEM” and noted that the kit seemed universal because one mount did not have a dedicated spot on their specific car. That is a common theme across these kits, so expect to possibly have one leftover bracket. The one-year warranty gives some confidence, but the 120 ratings are a smaller sample than the iKer’s 471, so the 4.7-star rating is less statistically sturdy. You get a better rust-resistant finish here than on the iKer set, but fewer reviews to back the quality claim.
What Stands Out
- Powder-coated metal brackets resist rust better than unfinished alternatives
- One-year warranty provides post-purchase support
- Very compact 6 x 6 x 2-inch package for easy handling
- Buyers confirm it stops engine vibration with an OEM-like fit
The Small Print
- One mount in the kit may not have a matching spot on every Altima
- Only 120 ratings — a smaller sample size than the top-rated competition
Choose it when: you want a rust-resistant, powder-coated set with a one-year warranty and do not mind if one bracket goes unused. It is the budget-to-quality standout for drivers in snowy or salty climates.
Pass if: you need a set where every single mount is guaranteed to bolt onto your exact car.
4. ENA Engine Motor Mount Set Compatible with Nissan Altima 2.5L
A clearly-labeled 4-piece kit with a 12-month warranty — no guesswork about what is in the box.
ENA’s set labels each of the four pieces: one transmission mount, one front torque strut mount, one rear motor mount, and one front right motor mount. That clarity is helpful — you know exactly what you are getting. The mounts are crafted from iron, aluminum, and rubber for a combination of strength and vibration dampening, and the steel construction is specified in the specs, unlike some competitors that only say “metal.” The dimensions are 10 x 9 x 9 inches, and the set weighs 4.72 kilograms — making it 5% lighter than the iKer set at 4.96 kilograms, though still hefty enough to feel solid.
Shoppers say that the mounts “work just fine for my car” and arrived super fast, with one reviewer noting good quality and proper function. The small review count of 49 means the 4.7-star average is less proven than the iKer set’s 471 reviews, but the detailed item description and the 12-month warranty suggest a brand that stands behind its product. The mounting locations are specified as front, rear, and right, so you know the coverage is complete. The main trade-off is the unfinished finish type means the metal brackets lack the corrosion-resistant coating that the Loongrie powder-coated set offers. You pay more for the clearest part breakdown and longest warranty.
Why It Is Worth It
- Explicit 4-piece set with each mount named (transmission, torque strut, rear, front right)
- 12-month warranty gives long-term coverage beyond most competitors
- Combination of steel, iron, aluminum, and rubber for durability and noise reduction
- Direct replacement design for proper fit and easy installation
Honest Limitation
- Unfinished metal is more prone to surface rust than powder-coated alternatives
- Only 49 ratings — a small sample size to confirm long-term reliability
Buy it if: you want a precisely-defined 4-piece kit with the longest warranty period and premium materials, and you prioritize clear product info over low price. The ENA set is for owners who want every part named before they buy.
Hold off if: you want a corrosion-resistant finish or prefer a set with hundreds of customer ratings to back up the quality claim.
Understanding the Specs
Rubber Durometer and Vibration Dampening
The rubber part of the mount is not just padding — its hardness (durometer) is tuned to the specific weight and torque of the 2.5L engine. A durometer that is too soft will crack and sag under the engine’s heat, while one that is too hard will transmit every small vibration into the cabin. The YEOPGYEON set is the only one that explicitly mentions durometer-matched rubber, which is a sign of intentional engineering for your Altima’s specific engine characteristics.
Kit Completeness: 4-Piece vs. Partial Sets
Your 2008 Altima uses multiple mounts — typically a front torque strut (a rod that controls engine twist during acceleration), a rear mount, and side engine and transmission mounts. If you only replace the one that looks broken, the others are likely near failure too. A full 4-piece set gives you balanced support and stops you from having to redo the job in a few months. The ENA and Loongrie sets explicitly label themselves as 4-piece kits, while the iKer set calls itself a “set” without specifying the exact count, so double-check that detail before buying.
