Bearing Door Type: All DD6 bearing doors have the same outer profile as a stock 5 speed so exhaust brackets, torque arms etc. fit like stock. The DD6 door comes with or without an ear. The ear door is for exhaust bracket mounting and does not fit 1993-2006 FL applications.

The ear door is for exhaust bracket mounting and does not fit 1993-2006 FL applications. Note the images below. The DD6 door bearings are larger providing 25% more dynamic load capacity than stock bearings used through 1998, also uses a 1/8″ bearing retainer plate instead of stock style snap rings.

FL Case Differentiations
To see an illustrated example of the differences between FL cases by year, please open the PDF here.
Gearset
All DD6 gearsets 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 gearset is a combination of helical and spur gears to yield silent gear operation. The dog teeth are backcut at a 1° angle to optimize the smooth shift possible, while standard gearsets are cut to a 4° angle. The mainshaft is unique with 1st main gear being incorporated as part of the shaft, the countershaft also features a unique 1-piece design with 6th gear.

Builder’s Kit Notes
Case Design
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 Upgrade
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).

Your input is very much appreciated. Share it with your friends so they can enjoy it too!
I had tried a few other upgrades and tweaks ... The 6-Speed Tran was the best yet. Now running at 2,500 RPMs at 65
This is the most complete kit I’ve ever used awesome
Shipping was fast. Great customer support.Great quality transmision. Installed with 3.24 1st in 1998 FLSTS Makuni carb,andrews ev23 cam. I'm very happy with this upgrade to my 98. First thru fifth no change in power or RPMs but ohh that 6th gear is nice.
The trans package slipped in perfectly, all adjustments were easy, take your time, read the instructions, watch the video
I had an excellent experience with my sales person She went far beyond what was necessary to help me.. she is a for sure keeper As for the product I still have not installed it yet but will be getting after it soon.
