Product Description
The BILSTEIN 24-185981 4600 Series Shock Absorber is engineered as a premium rear shock upgrade for 1999-2016 Ford Super Duty F250 and F350 trucks at stock ride height. Designed to improve ride quality, handling, and towing stability, this Bilstein B6 4600 shock delivers dependable control for daily driving, hauling, towing, and work truck use.
Built with Bilstein’s proven 46mm monotube gas pressure design, the 4600 Series provides consistent, fade-free damping performance under demanding conditions. The monotube construction helps dissipate heat more efficiently than conventional twin-tube shocks, helping your Super Duty maintain control on rough roads, loaded trips, and highway miles.
The velocity-sensitive digressive piston reacts quickly to changing road conditions, giving your truck a more stable, controlled feel without sacrificing comfort. This rear shock is application-tuned for stock height Ford Super Duty trucks and installs as a direct-fit OE replacement with no suspension modifications required.

FAQ
Will this fit a lifted Ford Super Duty?
No, the Bilstein 24-185981 4600 Series shock is designed for stock height suspension applications. Lifted trucks typically require a longer shock absorber.
Is this shock for the front or rear?
This part number is for the rear position on compatible Ford Super Duty F250 and F350 trucks.
Is this shock sold individually or as a pair?
This shock absorber is sold individually. For best ride quality and balanced performance, replacing both rear shocks at the same time is recommended.
What makes the Bilstein 4600 Series a strong upgrade over factory shocks?
Bilstein 4600 shocks use monotube gas pressure construction and digressive valving to deliver better control, improved stability, and more consistent performance than many conventional OE-style twin-tube shocks.
