Suspension Shock Absorber Rear Monotube Toyota Tacoma 2023-2016 B8 5100 Bilstein

The Bilstein B8 5100 (PN: 33-319070) is a rear monotube shock absorber built specifically for 2016–2023 Toyota Tacoma trucks running a 4-inch rear lift. This is not a universal shock shimmed to fit — it is vehicle-specific-tuned for that exact lift height, and it installs as a direct-fit replacement with a stem upper mount and 12mm eye lower mount.

The 46mm monotube body with a 14mm shaft runs a velocity-sensitive digressive piston that adjusts damping to road conditions in real time. Collapsed length is 16.48 inches, extended is 26.38 inches, with 9.9 inches of stroke travel — specs that matter when you're matching a shock to a lifted application. The smooth body, non-coilover design comes zinc plated and includes a black bellows boot. No reservoir.

We recommend this shock to Tacoma owners — SR, SR5, TRD Sport, TRD Off-Road, TRD Pro, Limited, Nightshade, Trail, and Trail Special Edition — who have already run a 4-inch rear lift and want a shock that was actually tuned for that configuration. Bilstein backs it with a limited lifetime warranty. If your rear end is wallowing or your current shocks are fighting your lift geometry, this is a direct path to consistent, fade-free damping.
