Dial In Your Ride with Bilstein's Dual-Speed Control

If you’re looking to give your 2015–2024 F150 4WD serious rear suspension performance, the Bilstein B8 8100 (DSA) Rear Shock is in a league of its own. The star of this setup is the Dual Speed Adjustment (DSA) technology, which gives you separate adjusters for both the high-speed and low-speed compression of the shock. This means you can fine-tune how your truck responds over small chatter bumps or larger impacts like ruts, washouts, and sudden drops. Whether you're driving on washboard roads, hauling overland gear, or just want to soften up your daily ride, DSA gives you precise control right at your fingertips. No guessing, no compromise; just the ability to adapt your suspension to whatever surface you're on. And with an external reservoir to boost oil capacity and reduce heat buildup, these shocks hold their composure long after stock dampers have faded.

Designed to Handle Every Adventure

The 8100 Series uses a large 60mm monotube body that holds more oil and allows for better heat dissipation, which directly translates into more consistent performance under stress. These shocks are also crafted from aerospace-grade billet aluminum components and finished in a sleek EVO Grey for durability and a clean look. Inside, the velocity-sensitive digressive valving reacts instantly to terrain changes, smoothing out rough surfaces without losing control or feel. Best of all, installation is straightforward thanks to a direct-fit design, with no need for custom fabrication or extra brackets. If you’ve already invested in larger tires or upgraded your front suspension, this rear shock is the perfect complement to keep your truck riding level, stable, and comfortable; on pavement, dirt, or anything in between.
