Hub Sprint Car P5 LH w/ Brake Mount

The Hub Sprint Car P5 LH with Brake Mount is a precision left-hand sprint car hub engineered for competitive oval track racing and high-performance sprint car builds. Built by Keizer Aluminum Wheels—a leader in lightweight racing wheel technology—this hub assembly is designed for drivers and fabricators who demand precision fitment, reliable brake integration, and the weight savings that translate directly to improved lap times. Sprint car enthusiasts know that every tenth of a pound matters when you're chasing positions on the track, and this left-hand configuration ensures proper weight distribution for balanced chassis dynamics.

Manufactured from aluminum alloy, the P5 hub minimizes unsprung weight while maintaining the structural integrity required for racing loads and repeated brake cycling. The integrated brake mount allows direct attachment of brake components without additional adapters, streamlining installation and reducing potential flex points in the brake system. At just 5.98 lbs, this hub exemplifies the lightweight engineering philosophy that defines modern sprint car setups—every gram saved on the wheel assembly translates to better acceleration, cornering response, and fuel efficiency over a race distance. The precision hub face and bore tolerances ensure concentricity with your wheel and axle, critical for eliminating vibration and maximizing tire contact patch consistency lap after lap.

This left-hand hub is ideal for drivers building or upgrading quarter-midget, 600cc sprint car, or other short-track racing platforms where weight reduction and brake system reliability are non-negotiable. Installation requires proper axle preparation and brake component alignment—work with your chassis builder or experienced fabricator to ensure the brake mount is squared and torqued to manufacturer specifications. The P5 LH configuration pairs seamlessly with Keizer's broader wheel and hub ecosystem, allowing you to source matching right-hand hubs and wheels for a cohesive, balanced setup that maximizes both performance and longevity on the track.
