Splined Hub Kit Sprint Axle Clamp 6 x 5.50in

The Splined Hub Kit Sprint Axle Clamp 6 x 5.50in from WILWOOD is a precision brake hub assembly designed for high-performance and race-oriented vehicle builds. This component serves as the mechanical interface between your brake rotor and axle, translating stopping power into reliable deceleration under extreme conditions. Whether you're building a dedicated track car, drag racing platform, or performance street machine, this splined hub kit ensures repeatable brake engagement and eliminates the risk of rotor slippage during hard braking events.

The 6-inch diameter and 5.50-inch bolt circle accommodate a wide range of custom and OEM brake packages, making this kit adaptable across multiple platforms. The splined hub design locks the rotor to the axle through positive mechanical engagement rather than friction alone, preventing rotor runout and ensuring uniform pad contact during repeated heavy braking cycles. WILWOOD's engineering maintains rotor parallelism and thermal stability, critical when managing the heat loads generated by performance driving.

This lightweight hub kit, weighing just 1.04 lbs, minimizes unsprung weight at the wheel, which improves suspension response and reduces inertia during acceleration and deceleration phases. Serious mechanics and enthusiasts choose WILWOOD brake components because they prioritize consistency and durability when stock solutions fall short. This hub kit integrates seamlessly into forced-induction applications, making it a versatile choice for performance upgrades.
