Suspension Shock Absorber Rear Monotube Toyota Tacoma 2023-2005 B8 5100 Bilstein

The Bilstein B8 5100 (24-186728) is a rear monotube shock absorber built specifically for the 2005–2023 Toyota Tacoma running 0–1 inch of rear lift. This is a direct-fit, vehicle-specific unit — not a universal shock trimmed to fit — which means Bilstein's engineers tuned the valving for Tacoma's exact suspension geometry and weight.

The 46mm monotube body and 11mm shaft are the structural backbone here. Monotube design keeps oil and gas separated, which eliminates fade under repeated compression cycles. The velocity-sensitive digressive piston reads changing road inputs and adjusts damping force accordingly — firm when the hit demands it, compliant when the road settles. Collapsed length is 14.02 inches, extended length is 22.94 inches, with 8.92 inches of stroke travel. Lower mount is an Eye 12mm; upper mount is a stem. Zinc plated finish. Black bellows boot included. No reservoir, no external adjustability — this is a set-and-forget rear shock.

We recommend this for Tacoma owners on stock height or up to 1 inch of rear lift who want meaningful ride quality improvement without touching the front suspension. It carries a limited lifetime warranty. MPN: 24-186728.
