Overdrive 6-Speed Gear Set delivers durable, quiet performance and smoother highway cruising. ⚙️🏍️
Includes trap door, all gears, mainshaft, countershaft, shifter drum, detent components, bearings, snap rings, gaskets and hardware for a complete installation.
Smoother shifting is achieved through a roller detent shift drum with reduced inertia and gear dogteeth with lead-in ramping for positive engagement.
The bearing door is machined from 6061-T6 aluminum and accepts wider bearings with a bearing retainer plate instead of the stock snap rings.
Gears are manufactured from 8620 steel, cut before heat treat and precision ground with diamond-coated tooling for quieter operation and longevity.
Lower engine rpm at cruising speeds improves comfort and fuel efficiency; exhaust bracket may require modification during installation. Made in the USA. 🇺🇸
