Hub Seal And O-ring Kit For Mini Sprint Hubs

The Ti22 PERFORMANCE Hub Seal and O-Ring Kit for Mini Sprint Hubs (TIP3572) is a precision-engineered seal assembly designed specifically for sprint car wheel hub applications where reliability under extreme racing conditions is non-negotiable. This kit delivers the exact dimensional specifications required for proper sealing and lubrication retention on mini sprint racing platforms.

The kit includes inner wheel hub seals with a 2.13-inch outer diameter and multiple bore diameters (1.285, 1.75, and 2.13 inches) to accommodate various hub configurations. The 0.311-inch thickness is engineered to provide the contact pressure and durability needed for sustained racing applications where heat cycling, vibration, and high cornering loads are constant. Constructed from steel and rubber compounds, the seals are compatible with both grease and oil lubrication systems—critical flexibility for teams adjusting setups between track conditions or following different chassis builders' recommendations.

This seal kit is essential for mini sprint racers performing hub maintenance, seasonal rebuilds, or bearing service. Sprint car racing demands seals that prevent contamination ingress while maintaining consistent lubrication film under repeated acceleration, braking, and lateral g-forces. The inclusion of o-rings within the kit ensures you have matched components for complete hub assembly, reducing the risk of incompatibility issues that could compromise bearing life or cause mid-race failures. Ti22 PERFORMANCE is recognized within the sprint racing community for manufacturing components that meet the precision standards competitive teams depend on.

Mini sprint racing places extreme demands on drivetrain reliability over short bursts of high-output power. Proper hub sealing is foundational to that reliability—it keeps contaminants out and lubricant in, which directly impacts bearing wear rates and wheel assembly longevity. This kit provides the OEM-specification seals needed to restore hubs to manufacturing standards or refresh aging components before competition season.
