Most of the 6 spd tranny makers just add an over-drive gear on the ratios stated above. This is true for the SE 6-spd. You can do this yourself with one of the Builder's kits from any of these mfgrs.
Baker, on the other hand, has the 6th gear as a direct drive with 1:1 ratio. This is more mechanically efficient than the over-drives. So they get the reduction in final drive with a change in the compensator sprocket and new chain. In fact, 1st through 3rd gears are straight cut (spur) for strength during maximum acceleration with no parasitic axial thrust. 4th and 5th gears are automotive style helical gears for quiet and smooth operation as highway speed approaches. 6th gear is direct drive which means there is no underdrive or overdrive in top gear which translates into 99% efficiency for minimum parasitic loss, minimum wear and tear, and maximum fuel efficiency. The Baker Builder's kit includes:
- Billet 6061-T6 bearing door
- 1/8″ thick bearing retainer plate
- Helical & spur gear design gear for quite operation
- 28 tooth compensator sprocket forged out of 8620 gear steel
- Regina double row primary chain
- Fat shoe chain tensioner w/hardware
- All transmission seals, gaskets and hardware
- 5 Year limited warranty

Re: six speed
PS - can you tell I favour the Baker tranny Yep and if not for Baker H D would probably still be working on building a 6 speed instead of refining the very stout 5 speed
