Sprint Inner Wheel Cover RR 14.25in Splined

The MPD Racing Sprint Inner Wheel Cover RR 14.25in Splined is a precision-engineered mud cover designed for right rear wheel applications on vehicles running 14.25-inch diameter wheels with splined mounting. This aluminum component features black anodized finish for corrosion resistance and durability in high-moisture racing environments.

Constructed from aluminum and finished with black anodize coating, this inner wheel cover provides protection against mud, water, and debris while maintaining minimal weight penalty—critical in competitive motorsports where unsprung mass directly impacts suspension performance and tire wear. The splined design ensures secure mounting without fasteners, allowing quick installation and removal during race prep or maintenance cycles. Weighing just 0.88 lbs, the sprint cover minimizes rotational inertia while the inner-wheel configuration keeps it concealed during normal operation, maintaining the intended aesthetic of modern race wheels.

This component is engineered for sprint car, dirt-track, and off-road racing applications where right-rear wheel protection from track surface hazards is essential. The inner design prevents mud buildup within the wheel structure, which would create centrifugal imbalance and reduce braking efficiency. Drivers operating in muddy or wet conditions benefit from reduced tire damage and cleaner brake cooling airflow.

MPD Racing specializes in lightweight, modular components for amateur and semi-professional motorsports. This sprint inner wheel cover is one component of a complete wheel protection system and is sold individually—specify right rear (RR) position when ordering to ensure correct fit relative to suspension geometry and brake duct orientation on your specific platform.
