With a piston diameter of 46mm and a shaft diameter of 14mm, this shock is built to withstand the rigors of off-road and heavy-duty driving conditions.

Common Applications and Problem Solving

• Improves suspension travel and control on lifted light trucks
• Reduces shock fade during extended off-road use
• Enhances ride stability on uneven terrain
• Replaces worn or damaged factory shocks for better durability
• Supports vehicles requiring remote reservoir shock absorbers

Installation Notes and Tips

Ensure compatibility with your specific light truck make and model before installation. The eye-type mounts require 12.8mm mounting hardware, so verify existing hardware dimensions. Since this shock absorber is non-adjustable, no damping tuning is necessary. The included billet reservoir clamp should be securely fastened to prevent movement during operation. Professional installation is recommended to maintain proper suspension geometry and performance.
