Suspension Shock Absorber Rear Monotube Toyota Tacoma 2004-1996 B6 4600 Bilstein

The Bilstein B6 4600 rear shock is a direct-fit monotube upgrade for the 1996–2004 Toyota Tacoma, including the 1998–2000 SR5. This is the drop-in replacement we recommend when OE shocks have worn out and you want a measurable step up in performance without lifting the truck.

The monotube design separates gas and oil into a single tube, which means consistent damping even under repeated hard use — no fade, no foaming. Bilstein's velocity-sensitive Digressive piston reads changing road conditions and adjusts response accordingly, so the shock tightens up when you need it and stays compliant on smoother surfaces. Critically, the tune on this unit is calibrated specifically for Tacoma applications — not a generic valving that's been adapted.

Specs worth knowing: collapsed length is 12.11 inches (307.5mm), extended length is 18.8 inches (477.5mm), with 16mm eye mounts top and bottom. Ships with a blue straight boot included. It replaces OEM part numbers 48531-09090, 48531-35500, 48531-80694, 48531-80697, and 48531-A9030. Non-adjustable, no external reservoir.

Bilstein backs this with a limited lifetime warranty. If you're running stock ride height on a 1996–2004 Tacoma and want a rear shock that outperforms OE without any fitment headaches, this B6 4600 is the call.
