2009 GMC Sierra 2500 HD Shocks and Struts

Ideal for vehicles with a higher center of gravity, Monroe® Reflex® light truck shock absorbers feature ASD valving technology that automatically adjusts the unit to absorb the impact, helping to reduce vehicle roll and dive.

Product Features:

• IMPROVES STABILITY — ASD (Acceleration Sensitive Damping) valving technology adjusts to impacts, reducing roll and dive for vehicles with a higher center of gravity
• EXCEPTIONAL HANDLING — Full displaced valving, tuned specifically to each vehicle, adjusts to road extremes while the larger bore provides more efficient damping control to provide consistency and a smooth ride
• CONSISTENT RIDE — OE all-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown while larger reserve tube holds more fluid to run cooler
• CONTROL AND DURABILITY — Fluon-banded piston provides consistent sealing between piston and pressure tube for better control and increased durability
• IMPROVES PERFORMANCE — Nitrogen gas charge maintains tire-to-road contact for improved ride and handling by reducing aeration
• 2-1/4 inch or 2 inch Diameter Reserve Tube: Allows more fluid carrying capacity for a cooler running unit.
• 1-3/8 inch Bore: Lower operating pressure than standard 1 inch bore units
• 5/8 inch Piston Rod: Heavy-duty nitrocarburized rod for long service life. On non-dust shield units only
• Special Seal: ‘Self-lubricating’ fluid seal designed to retain gas without excessive wear or friction.

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
