Features

• CrossTune Technology: A progressive engagement valving system provides a custom-tuned damping curve to ensure consistent control during both high-velocity impacts and low-speed maneuvers.
• Nitrogen Gas Charging: Pressurized gas displacement provides a reduction in aeration and shock fade to ensure peak performance during heavy hauling or off-road use.
• Heavy-Duty Body: A 2.25-inch reserve tube provides increased fluid capacity to ensure cooler operating temperatures during demanding cycles.

What is the benefit of the included dust boots?
The protective red boots shield the nitro-carburized piston rod from rocks, dirt, and road salt, extending the life of the internal seals.

Are these shocks sold as a complete set?
Yes, this specific SKU includes a full set of four shocks (front and rear) to completely refresh your vehicle’s damping system.
