Shock Kits

KYB Excel-G gas shocks and struts rely on velocity-sensitive valving to respond to changing road conditions for a smooth, comfortable ride. They feature sintered-iron pistons and guide rods for strength, hard-chrome piston rods for added durability, and seamless cylinders and eyerings that eliminate the typical weak points. Excel-G shocks and struts also have a patented check valve to minimize foaming and aeration and maintain control under tough conditions.

Ridetech HQ Series Shocks - The HQ (handling quality) Series shocks adds rebound adjustment for the driver who wants to tune ride quality AND handling quality to their specific taste. A wide rebound adjustment range allows you to cruise down the road in plush comfort or firm up your suspension for those Saturday morning canyon roads!
