Keep Your Super Duty Ready For Every Load

A hardworking truck deserves suspension that can keep pace with everything you ask it to do, and the Bilstein 24-185325 B6 4600 Rear Shock is built with exactly that goal in mind. Designed for 1999-2016 Ford F250 and F350 Super Duty 2WD trucks at factory ride height, this direct fit upgrade restores the confident handling and ride quality that worn factory shocks can no longer provide. Whether you are hauling equipment during the week or towing a trailer for the weekend, this shock helps keep the rear of your truck stable and composed. Additionally, the high pressure monotube design maintains consistent damping performance, so your suspension continues to perform even after long highway drives or rough backroads. Bilstein's application-specific tuning creates a balanced ride that feels comfortable without sacrificing control. The durable yellow finish and protective blue dust boot are built to stand up to daily exposure from dirt, rain, and road debris. If you want your Super Duty to feel dependable every time you load it up and head out, this rear shock is a smart upgrade.

Purpose Built To Enhance Factory Suspension Performance

The Bilstein B6 4600 Rear Shock is engineered as a direct replacement for stock height Super Duty 2WD applications, providing a straightforward installation with factory mounting locations. Its 46mm high pressure monotube construction improves heat dissipation, helping the shock maintain consistent performance under demanding driving conditions. Furthermore, the velocity-sensitive digressive valving reacts instantly to changing suspension movement, delivering precise control over both small road imperfections and larger impacts. This application-specific tuning reduces unnecessary rear suspension movement while improving stability, ride comfort, and towing confidence. The eye-to-eye mounting configuration features a 16mm upper eye and a 12.1mm lower eye for proper compatibility with the intended application. The smooth body, non-coilover design keeps the system simple and dependable, while the blue protective boot helps shield the shock shaft from dirt and debris. Backed by Bilstein's limited lifetime warranty, this rear shock delivers the durability, responsive handling, and long term reliability that have made the B6 4600 Series a trusted choice for stock height trucks.
