Product Description

The Rancho RS77066 RS7MT Rear Shock Absorber is a performance-tuned monotube shock designed specifically for lifted **2018-2026 Jeep Wrangler JL** models running approximately 2"-3.5" of rear lift. As part of the RS7MT Series, this shock offers a large gas-charged monotube design with advanced valving to deliver consistent damping and control over paved roads and off-road terrain. Its integrated dirt wiper sealing system helps protect critical internal components from moisture and debris, extending component life.

Built with a hardened chrome piston rod and PTFE-banded piston, the RS77066 is engineered to resist corrosion and deliver responsive ride quality under varied conditions. Internal rebound bumpers and rubber isolators help smooth out harsh impacts, while the deflective disc valving ensures balanced performance. Sold individually for rear driver or passenger side installation, this monotube shock is ideal for JL owners looking to improve rear suspension performance after a lift installation.
