Monroe Strut-Mate mounting kits are direct fit replacements designed to complement the ride control characteristics of Monroe struts. In addition, our full line will provide you with late model original equipment coverage. When doing strut replacements, it is important to do the complete job. This means not only replacing the struts but also inspecting and replacing worn strut mounts. Remember, worn strut mounts can adversely affect a vehicle’s safety and handling. Not only are strut mounts a necessary component of the suspension system, they consist of rubber to metal bonded parts that wear out over time as well. Worn bearings may also cause noise, steering binding, vibration and vehicle pull. Strut-Mate mounting kits can include:

Product Features:

• Strut Mount
• Bearing
• Upper Spring Isolator
• Lower Spring Isolator
• Upper Spring Seat

SACHS Suspension Strut Mount repair kits are designed to return the mount and bearing to Original Equipment standards.

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
