The Drive Spacer 1-1/8in ID x 1/16in OAL provides precise axial positioning for high-performance engine components. Designed primarily for marine and racing applications, this spacer ensures that pulley systems and crank mandrels maintain exact alignment under high-stress conditions. Boat owners and engine builders utilize these components to eliminate belt tracking issues and reduce parasitic drag on the drivetrain.
This Jones Racing Products component is machined from lightweight aluminum to provide durability without adding unnecessary rotational mass. With a 1.125-inch internal diameter and a specific 0.063-inch thickness, it allows for micro-adjustments in the spacing of mandrel-driven accessories. The natural finish provides a clean, professional appearance while maintaining the strict tolerances required for high-RPM marine powerplants.
Installation of the Drive Spacer 1-1/8in ID x 1/16in OAL is straightforward for those familiar with Jones Racing pulley setups and standard 1.125-inch mandrels. It is an essential part for fine-tuning belt tension and alignment in custom marine engine configurations where off-the-shelf spacing often falls short. Properly aligning your drive system with this precision spacer helps prevent premature belt wear and ensures maximum power delivery to your watercraft's vital systems.
