Cotter Pin Kit 3/16 x 4.0in S/L

The Cotter Pin Kit 3/16 x 4.0in S/L by WILWOOD is a precision fastener set engineered for high-performance brake system assembly and maintenance. Designed specifically for WILWOOD Superlite calipers, this kit contains 10 individual cotter pins that secure critical brake components and prevent fastener loosening under extreme vibration and thermal cycling. These pins are essential for any technician or enthusiast building or servicing performance braking systems where reliability and safety are non-negotiable.

Each cotter pin measures 3/16 inch in diameter by 4.0 inches in length and is manufactured from hardened steel with zinc plating for corrosion resistance and durability in demanding automotive environments. The zinc-plated finish protects against rust and oxidation while maintaining the structural integrity required for brake caliper pin retention. The split-leg design allows for quick installation and removal, spreading to lock the pin securely in place once inserted through the caliper pin hole, eliminating rattle and ensuring components remain positively secured throughout extended use.

Professional brake builders, racing teams, and brake system manufacturers rely on this WILWOOD cotter pin kit for OEM-quality caliper assembly and rebuilds. The set of 10 pins provides adequate inventory for multiple applications or replacement cycles, making it ideal for shops servicing WILWOOD Superlite brake systems on track vehicles, high-performance street cars, and racing platforms. Installation is straightforward—insert pins through the caliper pin holes and spread the split legs to lock. Compatibility with WILWOOD Superlite calipers ensures precise fit and function for critical brake safety applications.
