Suspension Shock Absorber Rear Monotube Toyota Tacoma 2023-2016 B6 4600 Bilstein

The Bilstein B6 4600 (24-265973) is a rear monotube shock absorber built as a direct-fit replacement for the OEM unit on stock-height 2016-2023 Toyota Tacoma — covering SR, SR5, TRD Sport, TRD Off-Road, Limited, Nightshade, Trail, and Trail Special Edition trims. No fabrication, no lift required, no new mounting hardware — it runs your existing OEM springs and factory mounting points.

The 46mm monotube design is the spec that matters here. Unlike a twin-tube setup, the monotube separates gas and oil into a single working chamber, which keeps performance consistent and fade-free even when the shock is cycling hard. The velocity-sensitive digressive piston adjusts damping force based on how fast the suspension is moving, so the ride doesn't feel harsh over small bumps but tightens up when it needs to. Collapsed length is 358mm (14.09 in); extended length is 581.7mm (22.9 in). Shaft diameter is 14mm. Lower mount is an eye-12mm; upper is a stem-type.

We recommend this shock to Tacoma owners who want a meaningful handling and comfort upgrade over OEM without changing ride height or trim geometry. The included blue straight boot protects the shaft, and Bilstein backs it with a limited lifetime warranty. If your rear shocks are due for replacement, this is the upgrade we'd put on the shelf over a stock reman.
