The Overdrive 6-Speed gear set delivers smoother shifting and lower rpm for improved highway comfort and fuel efficiency.
Includes trap door, all gears, mainshaft, countershaft, shifter drum, detent components, bearings, snap rings, gaskets and hardware.
Significantly smoother shifting than stock due to a roller detent shift drum with reduced inertia and gear dogteeth with lead-in ramping.
The bearing door is manufactured from 6061-T6 aluminum and features wider bearings and bearing retainer plates instead of the stock-style snap rings.
