The EFS Elite Rear Shock Absorber (36-5519) delivers outstanding comfort and stability for modern utes such as the Isuzu D-MAX RG and Mazda BT-50 TF 4WD. Designed for vehicles with a 45 mm suspension lift, this shock balances control, comfort, and off-road performance, making it ideal for daily driving, heavy loads, or remote touring.
With an open length of 626 mm and a closed length of 394 mm, it ensures extended wheel travel while maintaining stability and traction. Both upper and lower EB2 mounts provide secure, OE-style fitment. Inside, a 35 mm piston and 16 mm hardened-chrome shaft run within a 51–60 mm twin-tube nitrogen-gas body, tuned to resist fade under demanding off-road loads.
