Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure custom-tailored ride control for any load or trail condition.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
Simply turn the 9-position knob located at the base of the shock body to your desired setting; no tools or air lines are required.

Do these shocks provide the lift for my GMC K2500?
No, these shocks do not create lift. They are specifically valved and sized to function with vehicles already equipped with a 2.5 to 4-inch rear lift kit.

What setting should I use for towing?
Higher settings (7-9) are recommended for towing or heavy hauling to increase stability and reduce sway, while lower settings are ideal for daily street comfort.
