Quarter Midget Axle Belt Drive Sprocket Hub 1-1/4

The MPD Racing Quarter Midget Axle Belt Drive Sprocket Hub 1-1/4 is a precision-engineered sprocket carrier designed specifically for quarter midget racing applications. This aluminum component serves as the critical interface between your quarter midget's 1-1/4-inch axle and your belt drive system, translating engine power directly to the rear wheels with minimal loss. The black anodized finish provides corrosion resistance and durability through repeated thermal cycles and high-speed operation on the track.

Built from aluminum for lightweight strength, this hub features 7/16-inch mounting holes that mate with standard quarter midget frame rails and belt drive components. The 1-1/4-inch axle bore is precision-machined to ensure proper seating and concentricity—critical for eliminating runout that would otherwise cause vibration, belt slip, and premature wear on both the sprocket and drive system. At just 0.37 lbs, the hub minimizes unsprung weight without compromising structural rigidity. The black anodized finish resists oxidation in varying track conditions, maintaining a professional appearance through multiple race seasons.

This component is essential for quarter midget builders and teams who run belt drive systems and need direct-fit compatibility with 1-1/4-inch axles. Whether you're building a new quarter midget chassis or upgrading an existing drivetrain configuration, the MPD Racing sprocket hub ensures reliable power transfer and repeatable performance across multiple race events. The OEM-quality engineering and straightforward design make installation and maintenance straightforward for shop technicians and experienced builders.

MPD Racing is recognized in the quarter midget racing community for producing components that meet the precision and durability demands of competitive racing. This sprocket hub carries that same engineering standard—delivering the concentricity and structural integrity quarter midget racers expect from a trusted OEM supplier.
