Our Picks at a Glance
How To Choose The Best Upgrades for Your 09 Avalon Limited
Your 2009 Avalon Limited is a well-built machine, but age and sun take their toll. The key is matching the part to your exact problem without buying more than you need. Start with the symptom: is it dashboard glare, a failing blend door, or a bouncy ride? Each fix below has a specific job.
Dash Protection and Interior Care
If your dashboard is starting to fade or you hate the sun’s glare on the windshield, a custom-fit dash cover is the simple fix. Make sure it is precision-cut for the 2005-2010 Avalon to avoid wrinkles. A silicone-grip backing keeps it from sliding, and machine-washable polyester handles heat and spills.
Suspension and Ride Quality
For a smoother ride, complete strut assemblies are the way to go. They come pre-assembled with the coil spring, so your mechanic (or you) just bolts them in—no spring compressor needed. Look for a kit that includes sway bar links for a full front-and-rear refresh. The heavier the kit, the more hardware you are getting; a set weighing around 72 to 89 pounds includes everything you need for all four corners.

In‑Depth Reviews
1. HPEVA Dash Cover Mat
Our pick — over 4.5★ from 150+ verified ratings; the strongest balance of quality and price.
The custom-fit mat that stops windshield glare and protects your dash from sun damage.
This is the single most effective interior upgrade for your 2009 Avalon Limited. The dash cover mat is precision-cut for the 2005-2010 model, meaning it lays flat with no gaps or loose edges. The standout feature is the silicone-grip backing and Velcro strips that keep the mat planted even on bumpy roads, so you get no sliding or adhesive residue on your original dashboard.
It blocks 99% of harmful UV rays to prevent fading and cracking, and the anti-glare surface eliminates that blinding reflection off the windshield during sunny commutes. The pre-shrunk polyester is machine-washable and built to handle dust, spills, and heat. Buyers rate it 4.6 stars across 191 ratings, and fit is praised most of all—43 owners single it out. One owner says it is a “perfect fit and did not need the adhesive that came with it.”
At 1.0 count and a flannel material feel, it is a no-brainer first step to preserve your Avalon’s cabin.
Why Owners Love It
- Custom fit for 2005-2010 Avalon means no wrinkles or cutting
- Blocks 99% of UV rays to prevent dashboard cracking
- Machine-washable and easy to maintain
One Caveat
- A few owners note the adhesive patches aren’t needed, but some wish the grip was stronger without them
Reach for it if: you want a quick, effective fix for a sun-damaged or glaring dashboard and prefer a non-permanent solution.
Think twice if: you have a heavily textured dash that might prevent the silicone backing from sticking fully.
2. Metra 70-8215 Wiring Harness
The wiring harness that lets you upgrade your stereo without cutting factory wires.
If you want to replace the factory radio in your 2009 Avalon Limited, this harness is the professional way to do it. It keeps your climate control functions intact and lets you relocate the factory radio to the trunk if needed—which retains the info screen above the stereo, a common headache on these cars. The harness weighs just 0.25 pounds and comes with the steering wheel plug pre-wired with the needed resistor and aux plug.
Buyers rate it 4.2 stars across 80 ratings. One owner says “it made the work not too bad” even when they needed to relocate the factory radio for the info screen. Another notes the harness is “super convenient” because it avoids cutting factory wiring. A key detail: this harness is not for use in premium sound systems, so check your Avalon’s audio setup before buying.
A few owners have reported that the wire colors didn’t match on their installation, so double-check the fit using Amazon’s confirm feature or a multimeter.
Smart choice for: owners upgrading to an aftermarket head unit who want to keep their steering wheel controls, aux input, and factory info screen working.
Get this if: you are comfortable with basic car audio wiring and need a clean, no-cut harness for a non-JBL system.
skip it if: your 09 Avalon has the factory premium/JBL sound system—this harness explicitly does not fit it.
3. A-Premium HVAC Heater Blend Door Actuator
The part that fixes your Avalon’s hot-and-cold temperature mismatch, easily.
Is your driver’s side blowing hot air while the passenger side stays cold, or vice versa? That clicking sound behind the dash is a failing blend door actuator. This A-Premium unit is a direct swap for the 2005-2018 Avalon and matches OEM part number 8710607120. It weighs just 5.6 ounces and fits two locations in the HVAC box, so check your specific placement before ordering.
Buyers give it 4.2 stars across 181 ratings. The overwhelming take: it works. One owner says “we replaced this on our 2010 Toyota Highlander Limited… the part worked just fine” and calls it a better price than the dealer. Functionality is the most-praised aspect, with 19 owners highlighting it. Installation is simple—most owners use a stubby Phillips screwdriver and watch a YouTube tutorial. A helpful tip from one owner: loosely attach the screws first to align the planetary gear, then tighten them.
Some buyers report the fit can be tricky on certain model years, so use Amazon’s fit checker with your VIN or exact model details before buying.
Why It Works
- Matches OEM part 8710607120 for a direct replacement
- Most owners mention a 5-minute, DIY-friendly install
- One-year unlimited-mileage guarantee
Check First
- Fits main or left-main position only—verify your needed location
- Some owners on the 2007 Camry LE 4cyl reported fit issues
Buy it if: your Avalon’s HVAC is blowing uneven temperatures and you want a budget-friendly fix you can do in your driveway.
Look elsewhere if: you haven’t confirmed the specific actuator position your car needs.
4. Complete Struts Front & Rear Complete Strut Assemblies
A complete suspension kit that bolts in and gives your Avalon a smooth ride again.
When your 2009 Avalon starts feeling floaty or the ride gets bouncy over bumps, a full strut replacement is the fix. This kit from Complete Struts gives you all four corners: two front and two rear complete strut assemblies with coil springs already mounted. That means no spring compressor is needed—it is a direct bolt-in job for a mechanic or a confident DIYer. The whole kit weighs 72 pounds and comes with a one-year manufacturer’s warranty.
Buyers rate it 4.4 stars across 48 ratings, and every review describes a smooth result: “the product fitted perfectly on my Avalon 2011” and “the quality of these struts was very good.” One owner notes their mechanic only needed “a few things additional that was not included,” so expect to supply any small hardware or mounting bolts yourself.
While it has fewer reviews than the Detroit Axle competitor, the owners who bought it are unanimously satisfied.
Bottom line: a solid, no-nonsense suspension refresh for the Avalon owner who wants pre-assembled struts at a budget-friendly price. Works for model years 2006-2012.
Get this if: your Avalon’s ride has deteriorated and you want a simple, complete swap without dealing with spring compressors.
Note: the 72-pound weight is all steel and rubber—expect a solid feel on the road.
5. Detroit Axle 8pc Struts and Sway Bars Kit
The all-in-one suspension overhaul kit that includes struts and sway bar links for a complete refresh.
If you want to cover every wear point in your Avalon’s suspension in one go, this 8-piece kit from Detroit Axle is the answer. It includes 2 front struts, 2 rear struts (all with coil springs), plus 2 front and 2 rear sway bar links. That means you address the shocks and the anti-roll bar connections in a single purchase. The entire assembly weighs 88.78 pounds and features steel or aluminum construction. It comes with a 10-year warranty, which is exceptional for a suspension kit.
This is the most-reviewed product on this list: 4.3 stars across over 7,500 ratings. Quality is the top praise (403 mentions), with fit (354 mentions) and value for money (302 mentions) close behind. One owner says “my truck feels brand new” and another calls it “incredible value” after a 6-month review. Some owners note an initial bouncy feel that smooths out after a few hundred miles.
The catch is noise: 142 owners mention it, which is the most-discussed negative aspect. Some fitment issues on non-Avalon vehicles are also reported, but for the 2008-2012 Avalon it is widely considered a solid match.
Top Highlights
- 8-piece kit covers struts and sway bar links for a full suspension refresh
- Over 7,500 ratings with 4.3-star average speaks to wide buyer satisfaction
- 10-year warranty offers long-term confidence
Things to Know
- Some customers note noise after installation—check alignment and torque specs carefully
- Initial ride may feel bouncy for the first few hundred miles before settling
Best for: the owner who wants the most comprehensive suspension kit and doesn’t want to source sway bar links separately.
Heads up: the 88.78-pound kit is heavy, so you will want help moving and installing it.
Understanding the Specs
UV Protection Rating
In a dash cover, the percentage of UV rays blocked tells you how well it protects your dashboard from sun damage. A cover that blocks 99% of harmful UV rays prevents fading, cracking, and screen damage that sun exposure causes over time.
Weight and Kit Completeness
A complete strut assembly’s weight in pounds tells you how much hardware you are getting. A set weighing 72 to 89 pounds includes the strut, coil spring, and sometimes sway bar links. Heavier kits generally mean more metal components and a more thorough refresh of the suspension system.
