Help restore the factory ride height and handling of your 2007-2012 Lexus ES350 with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4402. This complete corner unit bundles the strut, mount, and spring into a single pre-assembled part for the rear right position, so you replace the whole worn corner in one step rather than piecing it together. A strut assembly supports vehicle weight, sets ride height, acts as the steering pivot, and helps control stability — and KYB builds this one as an OE-restoring unit designed to bring those capabilities back.
- KYB Excel-G strut: features a stronger steel outer shell and KYB's application-specific precision-designed damping valves.
- High-carbon steel coil spring: application-engineered to match the strut, help maintain proper ride height longer, and control weight without sacrificing ride quality.
- Side-specific design: left and right part numbers with side-specific design and components, as the vehicle manufacturer intended.
- Safety-system aware: engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.
Exact-fitment engineered and pre-assembled for professional results. Named the 2018 Best Overall Import Aftermarket Product. See the Buyer's Guide tab for engine details.
