Construction & Design:

The Rancho RS7MT shocks feature a robust monotube design with a large 2-inch diameter body that enhances heat dissipation and fluid flow for consistent damping performance. The piston utilizes a 46mm fluon-banded seal to ensure precise control and prevent fluid leakage, while the 14mm hardened chrome piston rod offers superior resistance to corrosion and physical damage. Double-welded loops at stress points and a hot-formed reserve tube provide added durability to withstand the rigors of off-road use.

An integrated dirt wiper sealing system protects the internal components from contaminants, extending shock life and maintaining smooth operation. The internal rebound bumper and shouldered rubber bushings reduce noise and vibration, contributing to a refined ride quality on all terrains.
