It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration.

The KYB Gas-a-Just monotube adaptive damper is a direct OE replacement designed for select Lexus vehicles equipped with adaptive suspension.

This rear shock absorber is engineered for straightforward installation and dependable operation in daily driving and performance-oriented conditions.
