When you search for the best struts for your Lexus RX350, you want options that balance comfort, durability, and value. The right set will transform your driving experience. Below are the top choices based on real-world performance and owner feedback.
OEM Lexus Struts
Original Equipment Manufacturer (OEM) struts are made by Lexus’s suppliers. They match the factory specifications exactly. If you want the ride quality your RX350 had when new, this is the safest bet.
- Perfect fitment and no modifications needed

- Available from dealerships or online parts retailers
OEM struts are ideal if you plan to keep your RX350 for many years. They offer no surprises. The ride remains plush and controlled, just like the day you drove it off the lot.
KYB Excel-G Struts
KYB is a major supplier to many automakers, including Lexus. Their Excel-G line is a direct replacement for OEM struts. They are known for restoring factory-like ride quality at a lower cost.

Gabriel struts are a budget-friendly alternative. They work well for short-term fixes or if you plan to sell the vehicle soon. Expect a slightly softer ride compared to OEM.
How To Choose The Right Struts For Your Rx350
Selecting the best struts depends on your driving habits and expectations. Consider these factors before making a purchase.
Driving Style And Comfort Preference
Think about how you use your RX350. Do you mostly drive on highways or rough city streets? Do you prefer a soft, luxury ride or a firmer, sportier feel?
- For a plush ride: OEM or KYB Excel-G
- For balanced comfort and handling: Monroe OESpectrum
- For sporty performance: Bilstein B6
- For budget: Gabriel Ultra
Your personal preference matters most. Test drive a similar vehicle if possible to feel the difference.
Vehicle Mileage And Condition
High-mileage RX350s may have other worn suspension components. Check your control arms, bushings, and sway bar links. Replacing struts alone might not solve all issues.
- Inspect all suspension parts before ordering
- Consider replacing strut mounts and bump stops
- Align the vehicle after installation
Ignoring worn parts can lead to premature strut failure. A complete suspension refresh is often worth the investment.
Budget Considerations
Strut prices vary widely. OEM struts can cost $200-$400 each. Aftermarket options range from $50 to $150 per strut. Factor in labor if you are not installing yourself.
- Set a realistic budget for parts and labor
- Cheaper struts may need replacement sooner
- Invest in quality if you plan to keep the vehicle long-term
Spending a little more upfront often saves money down the road. Premium struts typically last 60,000 to 80,000 miles.
Step-By-Step Guide To Replacing Struts On A Lexus Rx350
Replacing struts is a moderate DIY job if you have experience. Follow these steps carefully. Safety is critical when working with suspension components.
Tools And Parts Needed
Gather everything before you start. You will need basic hand tools and a few specialized items.
- Floor jack and jack stands
- Socket set and wrenches
- Torque wrench
- Spring compressor (essential for safety)
- New struts, strut mounts, and bump stops
- Penetrating oil for rusted bolts
Having the right tools makes the job easier and safer. Do not attempt this without a spring compressor.
Removal Process
Start by loosening the lug nuts on the wheel. Jack up the vehicle and secure it on jack stands. Remove the wheel.
- Remove the brake line bracket from the strut
- Unbolt the sway bar link from the strut
- Remove the lower strut bolts
- Remove the top strut nuts under the hood
- Carefully lower the strut assembly out
Work on one side at a time. Keep track of all bolts and hardware. Use penetrating oil on rusted bolts to avoid breaking them.
Disassembling And Reassembling The Strut
This is the most dangerous part. Use a spring compressor to compress the coil spring. Never remove the center nut without compressing the spring first.
- Compress the spring evenly on both sides
- Remove the center nut and top mount
- Transfer the spring to the new strut
- Install the new bump stop and dust boot
- Reinstall the top mount and tighten the center nut
- Slowly release the spring compressor
Double-check that all components are seated properly. A misaligned spring can cause noise and premature wear.
Installation And Torque Specifications
Install the new strut assembly in reverse order. Tighten all bolts to manufacturer specifications. Do not guess torque values.
- Top strut nuts: 29 ft-lbs
- Lower strut bolts: 156 ft-lbs
- Sway bar link nut: 33 ft-lbs
- Brake line bracket: 13 ft-lbs
Use a torque wrench for accuracy. Overtightening can damage components. Undertightening can cause looseness and noise.
Final Steps
After installation, lower the vehicle and tighten the lug nuts to spec. Pump the brakes a few times to seat the pads. Take the car for a short test drive.
- Check for unusual noises or vibrations
- Schedule a wheel alignment immediately
- Re-torque all bolts after 100 miles
An alignment is mandatory after strut replacement. It ensures even tire wear and proper handling.
Common Signs Your Rx350 Needs New Struts
Knowing when to replace struts can save you from unsafe driving conditions. Look for these warning signs.
Excessive Bouncing Or Nose Diving
If your RX350 bounces multiple times after hitting a bump, the struts are worn. Nose diving when braking is another red flag. Worn struts cannot control the vehicle’s weight transfer.
Uneven Tire Wear
Cupping or scalloping on the tire tread indicates suspension issues. Struts that cannot keep the tire planted cause irregular wear. Check your tires regularly for patterns.
Fluid Leaks On The Strut Body
Oil or fluid on the outside of the strut means the seal has failed. This leads to reduced damping and poor performance. Replace leaking struts immediately.
Vehicle Drifting Or Wandering
If your RX350 feels unstable at highway speeds, struts may be the cause. The vehicle should track straight without constant steering corrections. Worn struts allow excessive body movement.
Knocking Or Clunking Noises
Sounds from the suspension over bumps often indicate worn struts or mounts. Do not ignore these noises. They can lead to further damage.
