The EFS Elite Rear Shock Absorber (36-5521) is built to handle the toughest conditions while maintaining exceptional on-road comfort. Designed for multiple ute and wagon platforms running a 40 mm – 75 mm lift, this shock is part of the EFS Elite Series, engineered to balance strength, control, and comfort for touring, towing, or heavy off-road work.
With an open length of 626 mm and a closed length of 394 mm, the 36-5521 offers excellent suspension travel and consistent damping control. Both EB2 mounts ensure easy OEM-style installation. A 35 mm piston and 16 mm hardened-chrome shaft operate inside a 51 – 60 mm twin-tube nitrogen-gas body for fade-free damping and precise handling under load.
FEATURES
- Elite Series twin-tube nitrogen-charged design for maximum ride comfort and control.
