Rear Hydro Shock, 2.5-4" Lift, 73-91 Blazer

Rear Hydro Shock, 2.5-4" Lift, 73-91 Blazer.  Skyjacker Hydro and Nitro Shocks offer you a high quality shock absorber with true velocity sensitive valving.  Shock absorbers control the rate at which suspension springs compress and rebound.  As the shock is pushed together, this is called the bump or compression.  As the shock expands, this is called the 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.  Improve ride quality of your stock or lifted vehicle with a set of these Skyjacker shocks.  The durable long lasting action of the Skyjacker Nitro and Hydro shocks are designed to automatically adjust to any on or off-road conditions and they are backed by a limited lifetime warranty.
