Product Description

The Bilstein B8 5100 33-187471 is a rear shock absorber engineered for the 2009-2014 Ford F-150 in 2WD configuration running up to 1 inch of rear lift. Unlike the stock 4600-spec shocks, the B8 5100 is purpose-built for trucks running larger tires, a mild lift, or carrying heavier loads - situations where factory dampers begin to fall short. Its 46mm monotube construction with digressive valving delivers improved body control and a more composed ride, whether the truck is daily driven, used for towing, or pushed on rough terrain.

Installation is a straightforward bolt-on at OEM mounting locations across all cab styles and the full engine range of the 12th-generation F-150 platform. For 4WD applications, the correct part number is 33-187501. This shock pairs well with Bilstein 5100 front struts (24-317832) for a matched front-to-rear leveling system on 2WD trucks.
