Smooth Shift Kit

The design principles that made our Six-Speed Overdrive shift so smooth were applied to create a shift drum/pillow block kit that will bolt on to any 5-speed and give super smooth and precise shifting. The pillow blocks included with the kit are machined from our 6061-T6 extrusion stock for a significant increase in strength over stock. The roller shift drum features the same enhancements as the replacement 5-speed drum shown, as well as a revised detent profile for roller compatibility.

  • What model motorcycle do you ride? FXDWG 2004 - Bike of the Gods

Pricey but well worth the Canadian Peso

Real people, no bots, fun and knowledgeable. JT is very helpful in tech support on chat or get this live on a phone. They will even call you back. At some point you will need a bit or lot of guidance installing kit. I cabbed out shift drum, pawl, and lever. Just the nature of the process. You will then be glad you handed over money to this outfit. They deal and sell direct to me in Canada as network up here is useless.
