What makes the Rancho RS5000X shock absorber handle extreme temperatures?

The large twin-tube body is filled with all-weather fluid, which allows for cooler operation. This design helps the shock withstand internal temperatures ranging from -40 to 248°F, contributing to consistent performance.

How does this shock absorber help reduce damping fade?

The shock is pressurized with nitrogen gas to 150 PSI. This helps minimize the mixture of air and oil inside the shock, which is a common cause of damping performance fade and foaming.

Does this shock absorber come with a warranty?

Yes, this Rancho RS5000X shock absorber comes with Rancho’s Limited Lifetime Warranty, offering peace of mind for your purchase.
