Skyjacker Nitro Shock Absorber 2011-2011 Ram 3500 Crew Cab 4WD Regular Cab 4WD Extended Crew Cab 4WD

Skyjacker(R) Suspensions offers you a high quality shock absorber with true velocity sensitive valving. Shock absorbers, or spring dampers as it is called everywhere else except in the U.S., control the rate at which suspension springs compress and rebound. As the shock is pushed together, this is called bump or compression. As the shock expands, this is called rebound or extension. Absorbing the shock’ of bumps and suspension loading is actually performed by the springs in the suspension. The shock’s real job is controlling the energy stored in the springs.
