Description
If you’re running a 5-speed Harley Touring, Softail, or Dyna, you’re losing efficiency on the highway and putting unnecessary strain on your drivetrain. The JIMS 6-Speed Overdrive Super Kit converts your transmission into a modern 6-speed system that drops engine RPM by nearly 475 at cruise speed, reducing vibration, heat, and wear while delivering smoother acceleration and genuine long-distance comfort. This is a proven upgrade that pays dividends in both performance and component longevity.
Built and tested for 2001-2006 Harley-Davidson Touring, Softail, and Dyna models, the 8085L kit features close-ratio lower gears for responsive acceleration and a .86:1 overdrive 6th that transforms highway cruising. Installation is straightforward, though you’ll need a speedometer recalibration kit to ensure accurate reading after the upgrade.
