Features

• Nitrogen Gas Pressurized: High-pressure gas charging provides a consistent response and minimizes aeration to ensure fade-free performance during aggressive use.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock; simply turn the dial to your desired setting (1 for softest, 9 for firmest).

Will these shocks create a 4-inch lift on my truck?
No, these shocks do not create lift. They are specifically configured and valved for vehicles already equipped with a 4-inch suspension lift kit.

What is the benefit of the larger 2.75-inch shock body?
The larger body houses more oil, which dissipates heat faster than standard shocks, preventing the “fade” or softening of the suspension during long hauls or off-road use.
