Product details:

The Cross Tuned technology in Rancho's RS5000X series shock absorbers feature a patented progressive rebound and compression design to soften hard impacts and deliver a smooth, controlled ride at the same time. The stout 2-1/4" shock bodies are filled with more gas-pressurized fluid and feature nitro-carburized hardened piston rods and rebound dampers for longevity. Rancho's performance suspension systems have been blazing the trails since 1955.
