NITRO N8000 series shocks are recommended for full size vehicles and moderate to extreme off-road applications. Skyjacker(R) nitro 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

Get premium control and performance with Rancho RS9000XL shocks. Recognized as the first nine-position manually adjustable ride control series in the off-road market, RS9000XL shocks are ideal for on-road and off-road use, towing and more.

When an original equipment rear upper shock bracket on certain Chevrolet and GMC trucks rusts and fails, the dealer doesn’t offer a replacement, and fabricating a bracket can be time-consuming. The bracket, which sits at the front of the crossmember that also serves as the spare tire mount, is a little more difficult to install than others due to the curvature and construction of the crossmember. Make a professional repair by installing this Dorman OE FIX bracket, engineered to fit the crossmember just like the factory piece it’s replacing. This weld-on Dorman OE FIX rear upper shock bracket is constructed from quality carbon steel and designed to save time and money. It is engineered to precise dimensions and features a rust-resistant coating to help ensure long service life under the toughest on- and off-road conditions. The bracket is coated to prevent rust and speed installation – just recoat the appropriate areas after weld preparation and welding.

This shock mount insulator is precision-engineered and rigorously tested to provide reliable replacement for the original equipment on specific vehicles.

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.

When an original equipment front strut fails on certain GMC, Chevrolet and Cadillac SUVs and trucks equipped with magnetic ride control, it’s often due to fluid leaks that develop in the strut’s top seal assembly. Over time and miles, the factory seals deteriorate from the friction, heat and fluid pressure generated during every compression and rebound cycle of the strut. Ultimately that continuous cyclic load leads to seal failure and with it a loss of damping effectiveness and overall suspension performance, and potentially a failed state inspection. This Dorman OE FIX magnetic strut features an innovative upgraded top seal design that prevents this common and costly cause of strut failure. Our patent-pending top seal block assembly absorbs impact pressure better by more effectively and efficiently relieving and restoring cyclic fluid pressure on demand, virtually eliminating the relentless and damaging internal fluid pressurization inherent in the original equipment’s design. In addition, this strut features more durable mounting points to help ensure long service life under the toughest conditions.

Designed to restore a vehicle’s original factory drivability and performance, Monroe OESpectrum light truck shock absorbers provide an exceptional level of handling precision and control while filtering out noise, vibration and harshness.
