Product Description

The Bilstein 24-186704 B8 5100 Rear Shock Absorber is engineered as a direct-fit replacement for the rear suspension on 2004-2008 Ford F-150 2WD trucks and 2006-2008 Lincoln Mark LT 2WD models. Built with Bilstein's monotube design and high-pressure gas charge, this shock delivers improved stability, ride quality, and control compared to worn factory shocks.

Featuring a velocity-sensitive digressive piston and a robust 46 mm body, the B8 5100 rear shock responds instantly to changing road and load conditions, offering consistent damping performance. The zinc-plated finish protects against corrosion, while the bolt-on design ensures straightforward installation. Ideal for trucks used in daily driving, towing, and light off-road conditions, this rear shock helps restore confident handling and a smoother ride. Sold individually, two shocks are typically installed per vehicle for balanced suspension performance.
