Pulley Rear Fine Spline w/Yoke

The Pulley Rear Fine Spline w/Yoke (model 501-30037) from SWEET is a precision-engineered quick-change rear pulley assembly designed for high-performance power steering systems. Built for enthusiasts and professional fabricators working with custom drivetrains, this component enables rapid gear ratio changes and simplified maintenance on competition and street vehicles. The fine spline design ensures maximum engagement surface area and load capacity while maintaining quick-release convenience.

This pulley rear assembly features fine spline teeth that distribute torque across more contact points than coarse alternatives, reducing wear and extending component life under sustained load. The integral yoke design simplifies installation and alignment, eliminating the need for separate fasteners that could loosen under vibration. SWEET's quick-change mounting system allows operators to swap pulley ratios or configurations in minutes without removing the entire rear assembly, a critical advantage in race prep or prototype development. The compact profile—5 inches by 3.5 inches by 5 inches—fits tight engine bays without sacrificing structural integrity or load rating.

This rear pulley is ideal for builders integrating SWEET quick-change systems into custom power steering configurations, particularly in drag racing, road racing, and street rod applications where reliability and tunability matter. The fine spline geometry makes it compatible with standard SWEET quick-change rear mount platforms, ensuring drop-in fitment for qualifying installations. Weighing just 2 pounds, it adds minimal unsprung mass while maintaining the load capacity required for high-boost or supercharged engine applications. Verify yoke and pulley size compatibility with your existing drivetrain components before installation.
