Technical Details and Features

The Bilstein 25-329940 shock absorber features a monotube internal design with a 46mm piston diameter and a 14mm shaft diameter, providing precise control and durability. Its collapsed length measures 16.38 inches (416 mm), extending to 26.88 inches (682.7 mm) to accommodate suspension travel of 10.5 inches (266.7 mm). The zinc-plated finish enhances corrosion resistance, making it suitable for various weather conditions. Both upper and lower mounts use 12.8mm eyelets, ensuring compatibility with many light truck suspension setups.

Applications and Problem Solving

• Improves handling and stability on uneven or off-road terrain
• Reduces shock fade during extended heavy-duty use
• Restores suspension travel for lifted or modified trucks
• Enhances load carrying capacity by maintaining consistent damping
• Replaces worn or damaged factory shocks for improved ride quality

Installation Notes and Tips

Installation of the Bilstein B8 5160 25-329940 shock absorber requires compatible eye-type mounts with 12.8mm diameter. Ensure the vehicle suspension is properly supported before removal of old shocks. The included billet reservoir clamp should be securely fastened to prevent movement during operation. Since this shock is non-adjustable, no damping adjustments are necessary post-installation.
