Product Details and Specifications

This Bilstein shock absorber features a monotube internal design that ensures consistent damping performance throughout its stroke. The zinc-plated finish protects against corrosion, extending the service life of the shock. With a piston diameter of 46mm and a shaft diameter of 18mm, the shock is built to handle the demands of the Ford Bronco's suspension system. The shock's collapsed length is 16.62 inches (422.2 mm), extending up to 22.80 inches (579.2 mm), providing a stroke length of 6.18 inches (157.0 mm). The upper mount uses a stem design, while the lower mount is a crossbar type, compatible with the Bronco's factory mounting points. Note that this shock absorber does not include a boot or spring seat, so the OEM spring seat should be reused during installation.

Applications and Problem Solving

• Restores proper suspension travel and ride height on Ford Bronco light trucks
• Addresses worn or leaking factory shocks causing poor handling
• Improves stability and control on uneven or off-road terrain
• Reduces bottoming out and harsh impacts during suspension compression
• Supports suspension setups requiring ride height adjustment without complex damping changes

Installation Notes and Tips

When installing the Bilstein 24-313971 shock absorber on a Ford Bronco, ensure the OEM spring seat is retained as this part does not include a new seat. The snap ring grooved body design facilitates coilover compatibility, but verify fitment with your specific suspension setup. The upper stem mount and lower crossbar mount align with factory mounting points, simplifying installation. Since the damping is non-adjustable, no tuning is required post-installation. Proper torque specifications should be followed to maintain safety and performance.
