The EFS Elite Rear Shock Absorber (36-3299) is purpose-built for Jeep Wrangler JK LWB vehicles equipped with a 75 mm suspension lift. Designed as part of the EFS Elite Series, this twin-tube gas shock combines refined on-road comfort with dependable off-road control, ensuring consistent performance on any terrain.
Offering an open length of 635 mm and a closed length of 409 mm, the 36-3299 delivers balanced suspension travel and improved articulation. The Eye Bar Pin (top) and CR2-S (lower) mounts provide a secure OE-style fit, while a 35 mm piston and 16 mm hardened-chrome shaft inside a 51 – 60 mm twin-tube body ensure durability and fade-free damping under load. Low-pressure nitrogen gas keeps oil aeration in check, maintaining consistent shock response during long-distance or heavy-duty use.
