Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect balance between street comfort and off-road firmness.

Frequently Asked Questions

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

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and length-calibrated to work with vehicles already equipped with a 4-inch suspension lift.

What setting should I use for towing?
For towing or heavy hauling, it is recommended to use a higher setting (7-9) to increase damping resistance and improve vehicle stability.
