Bolt Kit

The WILWOOD Bolt Kit (MPN 230-0233D) is an essential fastener assembly for precision brake and suspension system builds. Engineered by Wilwood, a trusted leader in high-performance braking solutions, this bolt kit provides the critical hardware needed to secure brake calipers, rotors, and mounting brackets with confidence. Whether you're upgrading factory brakes to a track-capable big-brake kit or assembling a custom suspension geometry setup, proper fastener selection is non-negotiable—undersized or incorrect bolts can lead to caliper flutter, rotor runout, or catastrophic brake failure under hard cornering or emergency stops.

Wilwood bolt kits are manufactured to tight tolerances and use grade-appropriate materials to handle the cyclic loading, thermal stress, and vibration inherent in brake system operation. The kit's compact footprint—measuring 5.2 x 0.6 x 6.65 inches and weighing just 0.23 lbs—reflects a precision-machined fastener set that integrates seamlessly into brake assembly configurations without excess bulk. Each bolt is finished and prepared to resist corrosion and galling, ensuring reliable torque retention across repeated thermal cycles and hard braking events. The fasteners meet or exceed OEM specifications for brake system applications, providing the same level of quality assurance found in Wilwood's complete braking kits.

This bolt kit is ideal for brake system upgrades, restoration projects, and performance builds on vehicles ranging from street cars to road-course competitors. Installation is straightforward for technicians and enthusiasts with basic mechanical skills; apply a light coat of anti-seize compound to bolt threads, position the fasteners in brake caliper and mounting bracket holes, and torque to specification using a calibrated wrench or torque wrench. Proper bolt installation directly impacts brake system safety and longevity, making this Wilwood kit a reliable choice for anyone committed to quality brake work. Whether replacing lost fasteners or completing a full brake system overhaul, the WILWOOD Bolt Kit delivers the dependability required for confident, fade-free braking performance.
