Diaper Pin

The Diaper Pin by INTEGRA SHOCKS is an essential suspension fastening component designed for securing shock absorber preload and damper adjustment mechanisms on performance and off-road vehicles. This compact yet critical hardware piece serves as a retention pin for shock tower assemblies, ensuring that internal spring preload settings and dampening adjustments remain locked in place during aggressive driving, trail work, or high-impact terrain. Whether you're running coilovers on a track car, tuning a lifted truck, or maintaining factory shock hardware, the diaper pin prevents unintended loosening that can compromise suspension geometry and ride quality.

Manufactured to OEM specifications, this precision pin features a minimal footprint at just 2.55 inches in length with a 0.45-inch diameter, allowing it to fit into confined shock tower spaces without interfering with suspension movement or brake lines. The lightweight design—only 0.02 pounds—ensures zero unsprung weight penalty while maintaining the structural integrity required to withstand repeated compression cycles and vibration loading. The pin's compact profile makes it ideal for vehicles with tight engine bays or custom chassis setups where space optimization is critical, yet it delivers the holding force necessary for both street and competition applications.

This diaper pin is most beneficial for enthusiasts and mechanics rebuilding or upgrading shock systems, particularly those working with aftermarket INTEGRA SHOCKS coilover kits or adjustable damping systems. Installation requires basic hand tools and takes minutes, making it suitable for DIY suspension work or professional shop applications. Verify fitment against your specific shock model and year before ordering, as pin specifications can vary between platform generations and shock architectures. Keep spare pins on hand for maintenance intervals or track events where suspension components receive repeated cycling and adjustment.
