GMC Sierra 3500 HD Shocks and Struts

This Hellwig helper spring set the standard for all other aftermarket helper springs. Featuring progressive spring rate and fulltime spring rate design, this spring is the workhorse of the Hellwig spring line. With the Progressive design the vehicle must be loaded and its spring compressed to activate the Hellwig spring, therefore as the vehicles load increases the Hellwig helper spring progressively increases its resistance to the load. In the Fulltime design the Hellwig spring immediately reacts to the vehicles load, therefore compressing very little as load is applied to the vehicle. Manufactured with heat treated ASTM 5160 alloy spring steel these units increase your vehicles level load carrying capacity up to the manufacturer Gross Vehicle Weight Rating. Designed to install on full size pick-up trucks and vans, this unit requires mounting hardware to accommodate 2-1/2 Inch or 3 Inch wide leaf springs. Simple Bolt-On design using common hand tools provide the installer ease of installation and the vehicle owner hassle free use.

• Manufactured With Heat Treated ASTM 5150 Alloy Spring Steel. Increased Spring Rate And Stability
• Heavier Loads
• 4 Leaf Stack
• 3000 Pounds Level Load Capacity
• Available In Progressive Or Constant Rate
• Offers The Maximum In Carrying Capacity

HYDRO H7000 series shocks are recommended for multiple shock applications and mild to moderate off-road use. Skyjacker(R) hydro shocks, 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 real job is controlling the energy stored in the springs. The performance specific internal components of Skyjacker shocks respond to the on- and off-road conditions instantly. Whether you are going over rough or smooth terrain at slow or fast speeds, the true velocity sensitive valving produces a stable, controlled level of resistance for better handling, improved stability, and maximum comfort. The technological innovations of these durable, long lasting shocks from Skyjacker(R) deliver a noticeable advantage over the original equipment and other shock dampeners. Skyjacker shock absorbers deliver a safe, comfortable ride with improved handling and stability. They keep the tires in contact with the terrain and put you in control of the road ahead
