Design principles from overdrive systems were applied to create a shift drum and pillow block kit that bolts to any Cruise Drive 6-speed for super smooth, precise shifting.
The included pillow block is machined from high-strength extrusion stock for significantly greater strength than the original part.
- Redundant neutral feature and improved ratchet pawl geometry help the rider find neutral reliably.
- Advanced fork pin groove geometry and a linear detent bearing on the right-side mounting plate deliver smoother, more positive shifts.
- Fixed spindle drum reduces rotating friction, lowering the effort required to shift.
- Precision-machined spindle and drum maximize durability.
Gaskets and fasteners are included. Made in the USA. Installation is simple — no need to disassemble the stock gearset from the bearing door; remove the stock gearset and swap in the Smooth Shift drum. The kit reuses the stock shifter pawl, pawl centering pin, shift forks and fork rods.
Easy bolt-in upgrade for refined shifting on your Cruise Drive transmission. ⚙️
