Key Information

This shock absorber is a critical component for stabilizing the vehicle's suspension. It is engineered to dampen spring oscillation, manage road impact energy, and ensure consistent tire-to-road contact, which significantly improves handling and reduces wear on other suspension components. It typically includes a dust tube to protect the piston and internal seals from road debris, as well as a recoil cutoff feature to prevent damage during suspension overextension.
