This rear strut assembly with coil spring delivers exacting performance for 20042007 Toyota Highlander, 20042006 Lexus RX330, and 2007 Lexus RX350 front-wheel-drive models. Crafted for direct replacement, the unit arrives fully assembled to simplify installation and restore factory ride quality. The damper is charged with Japanese ENEOS damping oil, laboratory-tested for viscosity, density, and consistent function across an extreme temperature range of -40C to 80C. A thicker strut pipe and heavier-rate spring enhance structural intensity, while the spring undergoes over 600,000 fatigue cycles to confirm high tensile strength. Precise control of extension and compression dimensions matches the stock stroke, preserving the vehicles original handling character. Every damper endures three million fatigue endurance tests, ensuring leak-free operation and damping force attenuation that remains within 20 percent. With a package weight of 19.3 kilograms and dimensions of 78 by 36 by 22.5 centimeters, this assembly is engineered to meet the demands of discerning drivers who expect refined ride comfort and lasting composure.
