Strut Comparison Short Insights

When evaluating the best struts for lexus rx300, the biggest hurdle is identifying if your vehicle is AWD or FWD. Models like the COMPLETESTRUTS set are strictly FWD rear replacements, while OCPTY, Detroit Axle, and Readair explicitly target AWD compatibility. Using the wrong strut type can lead to improper ride height and poor handling.

For installation ease, almost all reviewed suspension products are complete quick strut assemblies. This is highly recommended as it avoids the dangerous step of compressing the old spring. Detroit Axle stands out by including sway bar end links in their rear kit, offering more comprehensive value.

If ride performance and stability are your main concerns, the KAX quick struts (both front and rear options) integrate advanced features like gas charging and heavy-duty load springs. Alternatively, OCPTY offers the most cost-effective solution if you need to replace all four corners simultaneously. Remember that items 7 and 9 are liftgate supports, not suspension parts, despite the term ‘struts’ being used.

Final Verdict: Choosing Your Best Struts For Lexus RX300

Deciding which struts are right for your RX300 depends heavily on your vehicle configuration (AWD vs FWD) and your driving needs.

The Best Overall Value (AWD Full Set): The 4xFront and Rear Strut Assembly by OCPTY wins here. Replacing all four corners at a competitive price, while maintaining the safety and convenience of quick-strut assemblies, makes this the simplest way to completely refresh an aging AWD RX300 suspension.

The Heavy-Duty Performer (Front): If your primary goal is front-end durability and load support, the KAX Struts Coil Spring Shock Absorber Assembly Front is the top choice. Its nitrogen-charged design and 5,000lb load rating offer a significant upgrade over factory specifications.

Best FWD Rear Fix: For FWD owners who just need to address the common rear sagging issue, the COMPLETESTRUTS Rear Quick Complete Strut Assemblies offers precise, guaranteed fitment for that specific drivetrain configuration, ensuring factory ride height is restored accurately.

Best Struts For Lexus RX300 FAQ

Q1: What are the main signs that I need to replace the best struts for lexus rx300?

A: Common signs of failing suspension struts include excessive bouncing after hitting bumps, severe dipping or “nosing” when braking, noticeable body roll when cornering, and the vehicle sitting lower than normal. You might also hear clunking noises over uneven surfaces or experience uneven tire wear.

Q2: Is it better to buy a full quick strut assembly or just the bare shock absorber?

A: For vehicles like the RX300, a quick strut assembly (or complete strut) is almost always recommended. It includes the shock, coil spring, strut mount, and boot, all pre-assembled. This saves significant labor time, requires no dangerous spring compressor tools, and ensures you replace all worn components simultaneously, guaranteeing optimal performance and a proper ride height.

Q3: Are the struts for the AWD RX300 different from the FWD model?

A: Yes, they are absolutely different, particularly the rear struts. The suspension tuning and the coil spring rates vary due to the weight distribution and drivetrain geometry of the All-Wheel-Drive system. You must purchase components specifically rated for your vehicle’s drivetrain (FWD or AWD) to ensure correct ride height and handling stability.

Q4: How long do replacement struts typically last on a Lexus RX300?

A: Quality aftermarket best struts for lexus rx300 usually last between 50,000 to 100,000 miles, depending heavily on driving conditions (city vs. highway) and climate. Components with features like advanced corrosion protection (such as the Readair kit) may last longer in harsh, snowy climates where road salt is used heavily.

Q5: Do I need to replace all four struts at once?

A: While it’s ideal to replace both front or both rear struts simultaneously to maintain balanced damping, replacing all four at once is usually only necessary if all four corners are equally worn. If you only notice issues on the front axle (often the case due to engine weight), replacing only the front pair is acceptable. However, kits like the OCPTY 4x package offer an excellent value if a full suspension refresh is overdue.

Q6: What is the difference between a suspension strut and a liftgate strut?

A: A suspension strut is a primary structural and damping component of the vehicle’s suspension system, affecting ride quality, handling, and safety. A liftgate strut (or gas spring) is a hydraulic component used only to assist in lifting and holding open the rear hatch or hood, having no impact on the vehicle’s driving dynamics. If your hatch is dropping, you need the liftgate strut replacement (like AiYiGu or YHTAUTO).
