Cotter Pin Kits 1/8 x 2.5in D/L & D/L Sgl

The Wilwood Cotter Pin Kit 1/8 x 2.5 inch (part number 180-0054) is a precision fastener set designed specifically for Dynalite and Dynalite Single brake calipers. These zinc-plated steel cotter pins secure critical caliper components and prevent fastener rotation or loosening during high-performance braking applications. As a dedicated brake component, this kit ensures proper caliper assembly and maintains safety-critical retention on track vehicles, race cars, and high-demand street applications where brake system integrity is non-negotiable.

Each kit contains 10 cotter pins manufactured from steel and zinc-plated for corrosion resistance. The 1/8-inch diameter and 2.5-inch length are engineered to match Wilwood's caliper specifications precisely. Zinc plating provides a protective coating that resists salt spray and environmental corrosion, extending service life in both road and track environments. Proper cotter pin installation prevents caliper pad retainer pins from backing out during braking cycles, a failure mode that can compromise brake performance and create safety hazards.

This kit is essential for anyone building, rebuilding, or servicing Wilwood Dynalite brake systems. Whether performing routine caliper maintenance, replacing worn fasteners, or assembling new brake packages, having OEM-specification cotter pins ensures assembly accuracy and reliability. The 10-count quantity provides replacement pins for multiple calipers or future service intervals, reducing downtime and ensuring you have spares on hand.

Wilwood brake components are widely used in motorsports, off-road racing, and performance vehicle builds. Using manufacturer-matched fasteners like these cotter pins maintains the integrity of the complete brake system and supports Wilwood's engineering specifications. For Dynalite caliper owners and builders, this kit is a straightforward, cost-effective way to ensure proper fastener retention and system safety.
