Skyjacker – Hydraulic, Limited Lifetime Warranty, Non-Adjustable, Includes Dust Boot, Single (Part No.H7027)

Hydraulic, Limited Lifetime Warranty, Non-Adjustable, Includes Dust Boot, Single

from

$55.99
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

Skyjacker – Nitro Shock W/Red Boot (Part No.N8036)

Nitro Shock W/Red Boot

from

$69.99
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

Product Features:
  • 150 PSI Pressurized Nitrogen Gas
  • Multi Stage Velocity Sensitive Valving
  • Twin Tube Construction. DOM Tubing Reduces Internal Wear For Longer Product Life
  • Bonded Iron Piston For Durability And Longer Shock Life
  • Chromed Piston Rod Features Micro Polished Shaft For Improved Product Life And Performance
