Rear Axle Spacer 7/8in Tapered w/Spline Black

The MPD Racing Rear Axle Spacer 7/8in Tapered with Spline in Black is a precision aluminum component engineered for sprint car rear axle assembly. This tapered cone spacer measures 0.875 inches thick and features 42-spline engagement, providing the exact axle offset and lateral positioning required for competitive sprint racing applications where wheelbase geometry and weight transfer directly impact lap times.

Manufactured from aluminum and finished in black anodize, this spacer delivers the precision tolerances sprint car builders demand. The tapered design ensures consistent engagement with the spline, eliminating play that can compromise handling predictability. At just 0.24 lbs, it adds minimal unsprung weight while maintaining the structural integrity necessary for high-load racing environments. The 42-spline configuration is the standard interface found on most sprint car axle systems, ensuring compatibility with common rear end assemblies used in both winged and non-winged competition.

This spacer is essential for teams building or maintaining sprint car rear ends where precise axle positioning is non-negotiable. Whether you're setting up a new rear assembly or replacing worn components, the correct spacer thickness ensures proper brake balance, tire loading, and lateral weight distribution across the axles. MPD Racing spacers are widely used in regional and national-level sprint car competition, where repeatability and dimensional accuracy are fundamental to competitive success.

Rear axle spacers are often overlooked in chassis setup discussions, but they play a direct role in how a sprint car handles through corners and on straightaways. The 7/8-inch tapered design is a common spec in the sport, making this an ideal replacement or upgrade component for teams running established rear end packages. Sold individually, allowing builders to purchase the exact quantity needed for their specific rear assembly configuration.
