Technical Description and Features

This Bilstein shock absorber utilizes a monotube internal design, which improves heat dissipation and maintains consistent damping performance under demanding conditions. The zinc-plated finish enhances corrosion resistance, extending the service life of the shock. With a piston diameter of 46 mm and a shaft diameter of 18 mm, this shock absorber is engineered to handle the weight and dynamics of light trucks like the Ford Bronco. The snap ring grooved body allows for coilover compatibility, while the eye lower mount and stem upper mount ensure secure attachment to the vehicle's suspension system. Note that the damping is non-adjustable, providing a fixed performance characteristic optimized for ride comfort and control. The shock absorber’s stroke length of 8.45 inches supports effective suspension travel, contributing to improved handling and stability.

Applications and Problem Solving

• Restores proper suspension travel and ride height on Ford Bronco models
• Reduces excessive body roll and improves vehicle stability
• Addresses worn or leaking OEM shocks causing poor ride quality
• Enhances off-road capability by maintaining consistent damping
• Supports suspension setups requiring coilover compatibility

Installation Notes and Tips

When installing the Bilstein 24-313988 shock absorber on a Ford Bronco, ensure the OEM spring seat is reused as this part does not include a spring seat. Verify the correct orientation of the eye lower mount and stem upper mount for proper fitment. Due to the non-adjustable damping design, no additional tuning is required post-installation. It is recommended to inspect all suspension components for wear during installation to maintain optimal performance.

The zinc-plated finish provides corrosion resistance suitable for various driving conditions. While specific warranty details for part number 24-313988 should be confirmed with the manufacturer or distributor, Bilstein typically offers coverage against defects in materials and workmanship.
