750136 Inner Primary to Motor Spacer Ring Available in Chrome Plate

This Zodiac primary offset component is designed for custom Harley-Davidson builds requiring wide rear tyre clearance without setting the engine off-center. It facilitates the outward displacement of the primary drive system using extended motor sprocket shafts and spacer rings. For larger offsets such as 45mm and 55mm, the spacer rings feature an integrated support bearing to mitigate increased crankshaft load. These components are essential for maintaining drivetrain integrity when moving the transmission or primary drive to accommodate oversized rubber. Zodiac's precision engineering ensures these hardware pieces withstand the mechanical stresses of high-torque V-twin applications, providing a reliable solution for complex chassis modifications and custom frame alignments.
