The KYB 7240000 Gas-A-Just Rear Adaptive Shock is a premium aftermarket shock absorber engineered as a direct OE replacement for Lexus vehicles equipped with adaptive suspension. Featuring a high-pressure monotube design, this shock delivers improved handling precision, balanced ride comfort, and responsive damping control by automatically adjusting to changing road surfaces and conditions.

Ideal for drivers looking to restore original ride quality and suspension performance, the Gas-A-Just technology helps maintain stability, control, and confidence on daily drives or more demanding road conditions. Always verify your vehicle's suspension type (adaptive vs non-adaptive) before purchasing to ensure compatibility.
