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

PRECISE HANDLING AND PERFORMANCE — Deflective Disc Valving features digressive, linear or progressive tuning based on application requirements for precision handling and performance on- and off-road
STRONG AND DURABLE — Features a 14mm hardened chrome piston rod to resist scuffs & corrosion, double-welded loops at stress areas, double strength closure method and hot form reserve tube
HANDLES EXTREME TEMPERATURE CHANGES — Large 2-in. monotube body filled with all-weather fluid allows for cooler operation, increased vehicle control and ability to withstand internal temperatures of -40 to 248 Deg. F
REDUCES FADE — Full-floating dividing piston and high-pressure nitrogen gas maintains constant pressure against the hydraulic oil, reducing aeration and shock fade
SMOOTH PERFORMANCE — Internal rebound bumper and shouldered rubber bushings help reduce noise, vibration and ride harshness while the PTFE-banded piston enhances responsiveness to changing road conditions for an overall smoother ride
THE RIGHT FIT — Designed to fit right out of the box, application-specific mounting installs easily with no need for installing sleeves or extra hardware
KEEPS DIRT AND DEBRIS OUT — Sealing system with integrated dirt wiper helps keep moisture, dirt and debris from being ingested into the shock and contaminating the oil and destroying the internal seal
BUILT TO LAST — Large 46mm fluon-banded piston for consistent sealing between the piston and monotube for precise control, ride and handling; for extra protection, purchase shock boot RS1952 or RS1961
