• Paired rear shock absorber: Bilstein 24-313988.
• Sold as a single unit. Install in pairs for balanced front axle performance.

Product Description

The Bilstein 24-313971 is a front B8 5100 Ride Height Adjustable shock absorber designed specifically for the 2021-2025 Ford Bronco 4-Door. Unlike standard fixed-length shocks, the adjustable snap-ring groove design allows you to dial in 0-2.9" of front lift using your existing factory coil springs - no spring swap required. This makes it the simplest and most cost-effective way to level or lift the front of your Bronco while simultaneously upgrading damping performance beyond the entry-level HOSS 1.0 setup found on Base, Big Bend, and Outer Banks models.

The 46mm monotube gas-pressure design delivers consistent, fade-free performance whether navigating daily commutes, highway miles, or demanding off-road terrain. Installation is a direct bolt-on using factory mounting hardware, and the shock pairs with Bilstein 24-313988 at the rear for a complete four-corner upgrade. Compatible with all non-Raptor 4-Door Bronco trims and fully compatible with the Sasquatch Package.
