When Your Truck Deserves More Than Stock Suspension

If you’ve lifted your Super Duty and still haven’t upgraded the shocks, now’s the time to fix that. The Bilstein 24-285285 B8 5100 Series Front Shock is built for owners who push their trucks harder than the average daily driver. Whether you're towing heavy gear, tackling uneven roads, or just want more control at highway speeds, this shock delivers a noticeable difference in ride quality. It's built specifically for 2017–2025 F-250 and F-350 4WD trucks with a 4-inch front lift, so you’re not guessing whether it’ll fit. The ride feels more stable, body roll is reduced, and small bumps don’t throw your truck off balance like they used to. It also gives your suspension the ability to react faster when road conditions change, which means more control and comfort no matter where you're headed. If you're already running a lift, this is the upgrade your suspension is begging for.

Built With The Precision Your Suspension Needs

The Bilstein 24-285285 features a true monotube design that uses a 46mm steel body and a velocity-sensitive, digressive piston to ensure consistent performance under stress. That piston reacts instantly to changing road conditions, allowing your truck to adapt quickly whether you're crossing gravel or pulling a trailer down the interstate. Its zinc-plated finish fights corrosion over time, while the 14mm chrome-hardened piston rod adds durability for harsh environments and heavy loads. Each shock is tuned for its specific application, so it isn’t a generic one-size-fits-all solution. It's designed to provide fade-free performance even when the shock is cycling under repeated pressure, and that makes a real difference for trucks that see serious use. With a collapsed length of 16.85 inches and an extended length of 25.75 inches, this shock is optimized for trucks with a 4-inch front lift. Best of all, it bolts directly in place with no modification required, making it a clean upgrade for any lifted Super Duty build.
