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.
- One-piece countershaft with 5th gear
- Larger door bearings
- Billet 6061-T6 chrome door for strength
- Hard chrome plated shift forks for wear resistance
- Smooth roller shift system with Redundant Neutral vastly improves neutral finding
- 5 Year limited warranty
All DD5 bearing doors have the same outer profile as a stock 5 speeds 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 does not fit 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.
Our 5 Speed shift system with roller detent guarantees smooth shifts every time and our redundant neutral ensures that finding neutral is a 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

All DD5 gearsets come with a 1-piece counter shaft. Eliminates the well known Achilles heel of the stock 5-speed under high horsepower and/or heavy GVW applications. That is, the 5th gear cracks radially and splits in half with catastrophic results. Our one piece design is good to 200 H.P. All gears are made out of 8620 steel, gears are shaper cut before heat treat then precision ground with diamond coated tooling after heat treat (58-62 Rockwell ‘C’). This extra steps ensures not only a quieter gear pair, but enables much tighter backlash control.
The DD5 comes in a standard, optional or R-Ratio configuration. A way to physically tell which ratio you have is pretty common knowledge here at BAKER, but if you would like to know look at the 1st gear pair on the gearset. Our standard 2.94 1st gear will not have a notch on the 1st countershaft gear, our (stock) 3.24 1st gear will have a single notch around the center of the 1st countershaft gear and our 2.82 (R-Ratio) 1st gear will have 2 notches around the 1st gear countershaft. Use the image on the far right for reference. This is very important to know if you need any replacement parts or components.
Our billet shift forks are 3x thicker than stock and hard chrome plated for wear resistance

-Change ’0′ in PN to ’1′ to specify a 3.24 1st gear ratio; EX: PN 501 changes to PN 511
-Change ’0′ in PN to ’21′ to specify a “R” ratio; EX: PN 501 changes to PN 5211
Complete Build Case Finish Options
Add the suffix to the end of the PN for case finish; ‘R’- Raw finish, ‘B’- Wrinkle Black finish, ‘P’- Polished finish and ‘C’- Chrome finish (Chrome Available only on 1990-97 Softail Billet Cases).
The BAKER Softail case design had all leak potentials in mind during the design. We added stud pads to the inside of the case so that the thread holes for the transmission studs were blind holes, NOT through holes like some aftermarket brands. Looking at the image on the right you can see the difference.

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).
