Our BAKER DD5 is not just a replacement for the stock 5-speed. Whether you’re going down the drag strip or you’re cruising down the road, the torque capacity, long-term durability, and shift quality are greatly improved over stock. Will handle up to 200 H.P. no problem.
The DD5 Builder's Kit comes with a polished bearing door.

Benefits
- Handles over 200 ft/lbs of torque (more than stock)
- Easier to find neutral
- Smoother shifting
- Longer-lasting components
Fitment
-
1990-2006 Big Twins* (except 2006 Dyna)
*1990 models must purchase and use a High Torque Bearing Kit (PN 189-56).
Bearing Door Type: All DD5 bearing doors have the same outer profile as a stock 5-speed, so exhaust brackets, torque arms, etc. fit like stock. The DD5 door comes with or without an ear. The ear door is for exhaust bracket mounting and the non-ear door fits 1993-2006 FL applications.
Mainshaft: The 1991 style splined mainshaft comes standard on the DD5 Builder’s Kit.
1st Gear Ratio: The 2.94 1st gear ratio is a good all-around ratio.

Detail
DD5 Builder’s Kit Layout
Bearing Door
All DD5 bearing doors have the same outer profile as a stock 5-speed, so exhaust brackets, torque arms, etc. fit like stock. The DD5 door comes with or without an ear. The ear door is for exhaust bracket mounting and the non-ear door fits 1993-2006 FL applications. Note the images below. The DD5 door bearings are larger providing 25% more dynamic load capacity than stock bearings used through 1998.
Shift System
Our 5 Speed shift system with roller detent guarantees smooth shifts every time and our redundant neutral ensures that finding neutral is an easy chore. We mount a plunger detent on the left side pillow block and cut a plunger track into the shift drum itself. The plunger follows this track during operation (shifting) and when shifting into neutral pops into a pocket. This system lets you feel that you’re shifting into neutral. No more guessing. Shift drum features more aggressive timing on the fork groove profiles and is case hardened to 58 Rockwell for wear resistance and crisp shifts. We built our reputation on smooth-shifting 6-speed transmissions; our 5-speed drum designs benefit from the engineering lessons learned.
FL Case Differentiations

Gearset
All gears are made out of 8620 steel, hobbed before heat treat, and then precision ground with diamond coated tooling after heat treat (58-62 Rockwell ‘C’). These extra steps ensure a quiet gear pair with minimal backlash.
Ratios
The DD5 comes with a 3.24 or 2.94 1st gear ratio.

Special Note
- Speedo recalibration unit is required for electric speed sensor applications; PN 95E-56B.
Recommended Fluid / Level
Picking the right transmission fluid ensures the life and durability of your transmission, that’s why BAKER recommends a fully synthetic GL-5 rated gear weight oil of 75W-140. If a GL-5 rated gear lube is not available, these commonly carried viscosities (weights) will work 75W-90, 75W-140, and 85W-140. BAKER does not recommend the use of Syn3 (20W-50).
