The Bilstein B6 4600 rear shock absorber (part 24-185073) is a monotube gas damper built for the 2005–2015 Toyota Tacoma RWD with 5-lug wheels at stock height (0" lift). It uses a stem-style upper mount and an eyelet lower mount, with a yellow paint finish, no external reservoir, and non-adjustable damping. Shoppers searching for a 2005 Tacoma RWD rear shock upgrade, B6 4600 monotube rear shock, or stock-height Tacoma RWD rear damper replacement will find it matches the factory setup. It is a direct-replacement damper, not a lift or adjustable coilover kit. Choosing this over a generic budget shock comes down to the Bilstein name, a limited lifetime warranty, and a like-for-like replacement for a worn factory unit. The shock is not compatible with trucks equipped with air leveling suspension or Nivomat systems, so confirm your rear suspension before ordering. The rear mounts are a straightforward swap for most DIY owners, but check that the mounting hardware and bushings you need are included with your order, since the set contents vary between listings.
