Axle Spacer System For Midget 36 Spline

The Axle Spacer System for Midget 36 Spline by MPD Racing is a precision engineering kit designed for circle-track racing applications, particularly midget racers requiring adjustable axle geometry and load distribution. This spacer system allows drivers and crew chiefs to fine-tune rear-end setup by altering pinion angle, gear preload, and side load characteristics—critical adjustments for optimizing traction and handling on dirt or asphalt surfaces. Whether preparing for weekly racing or high-level competition, this modular kit provides the flexibility needed to dial in performance across varying track conditions.

This kit comprises two 0.25-inch straight spacers, four 0.5-inch straight spacers, one 0.500-inch male cone, and one 0.625-inch female cone, all machined from lightweight aluminum to minimize unsprung weight while maintaining dimensional stability. The 36-spline design ensures compatibility with standard midget axle shafts and differential housings, providing secure engagement without play. The tapered cone components allow for progressive geometry adjustments, enabling crew members to stack configurations in various combinations to achieve precise pinion angles and preload settings without requiring different axle components or major teardown procedures.

Midget racing teams and shop professionals benefit most from this modular approach, as the system reduces downtime during setup changes and eliminates the need for purchasing multiple axle assemblies for different track conditions. Installation requires basic tools and familiarity with rear-end assembly procedures; spacers are simply stacked on the axle shaft before installation into the housing. The aluminum construction keeps total kit weight at just 0.92 pounds, ensuring minimal impact on vehicle dynamics while the 36-spline specification guarantees proper fit on Midget-class racing platforms from leading manufacturers.
