V-Twin Mfg 0.600 Inch Transmission Sprocket Conversion Spacer Kit for 1984-1993 Harley-Davidson
Modernize the drivetrain of your early 5-speed Big Twin with this professional-grade conversion kit. Designed specifically for 1984-1993 Harley-Davidson models, this kit allows the installation of 1994-2006 style transmission pulleys or sprockets. By upgrading to the later style configuration, you gain access to a wider range of final drive ratios and increased parts availability for custom belt-to-chain conversions or wide tire applications.
This comprehensive kit includes everything needed to complete the transition, ensuring a leak-free and secure installation. It features the essential 0.600 inch spacer that compensates for the offset difference between early and late style output shafts.
