Hub Cap Screw In Sprint Kit

The WINTERS Hub Cap Screw In Sprint Kit (Part No. 3749-01) is a precision-engineered drive flange dust cover designed specifically for sprint car hub applications. This screw-on aluminum component provides essential protection against dirt, moisture, and debris contamination of the wheel bearing assembly—critical for maintaining consistent brake and suspension performance in high-speed racing environments where component reliability directly impacts lap times and safety.

Constructed from aluminum and finished in black anodized coating, this hub cap delivers both corrosion resistance and lightweight durability. The anodized surface resists oxidation from moisture exposure and brake dust while maintaining a professional appearance. The screw-in design allows for straightforward installation and removal without requiring specialized tools, making it practical for pit work and maintenance routines. At 0.27 lbs and measuring 3.8 x 1.65 x 3.9 inches, it integrates seamlessly into existing sprint car hub assemblies without adding unnecessary weight or complexity to the unsprung mass.

Sprint racing demands consistent performance across repeated heat cycles and competitive events. This hub cap protects bearing seals from contamination that can accelerate wear, reducing maintenance intervals and extending component lifespan. Whether prepping for a weekend series or maintaining a competitive racing program, the WINTERS hub cap is a cost-effective insurance policy against unexpected bearing failure and downtime. Serious racers and fabricators building or maintaining sprint cars will recognize WINTERS as a manufacturer focused on precision sprint car components rather than general aftermarket parts.
