Product Description

The Bilstein 24-185325 is a B6 4600 series rear monotube shock absorber designed as a direct-fit upgrade for the 1999-2016 Ford F-250 and F-350 Super Duty in 2WD configuration. The 46mm monotube body allows for a larger piston and superior heat dissipation compared to twin-tube designs, delivering consistent, fade-free damping during daily driving, heavy hauling, and towing. The velocity-sensitive digressive piston automatically adjusts to changing road conditions for improved control without sacrificing ride comfort.

Each shock is application-tuned specifically for the F-250/F-350 platform and features a corrosion-resistant yellow zinc finish. Installation is a direct bolt-on replacement of the factory rear shock with no modifications required. Sold individually -- two required for a complete rear replacement. Backed by Bilstein's limited lifetime warranty.
