Frequently Asked Questions
What does this shock absorber do?
It dampens suspension movement to control ride motion and help keep the tires in contact with the road. This RS5000X uses Rancho's Cross Tuned valving to improve on- and off-road handling.
Where does the RS55297 mount?
It is cataloged as a rear-position shock absorber for the listed applications. Confirm your vehicle in the Buyer's Guide tab before ordering.
Is it gas-charged?
Yes. It is nitrogen gas pressurized to 150 PSI, which helps minimize air-to-oil mixing to reduce damping performance fade and foaming.
What are signs my shocks may need replacing?
Excessive bouncing, nose-dive under braking, body sway, uneven tire wear, or fluid leaking from the shock body are common signs the shocks may be worn.
Should I replace both rear shocks together?
It's a best practice to replace shocks as an axle pair for balanced, even ride control. This listing covers one shock, so order two for the rear axle if needed.
