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.

All DD6 bearing doors have the same outer profile as a stock 5 speeds 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. 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.
Our 6 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 drum designs benefit from the engineering lessons learned.
FL Case Differentiation

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.

Our investment cast shift forks are made out of 4140 then dipped in a hard chrome plate bath for wear resistance, also designed with oil reliefs to ensure proper lubrication and wear resistance on fork blades and shift dogs.

Complete Build Notes
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.

I went with the 28 tooth comp sprocket (36 tooth clutch basket) and the optional 2.94 first gear. I just built my motor (1340 Evo with headwork, high-lift cam, 10:1 pistons and Dynatec 2000i ignition), so I am still taking it easy breaking everything in, haven't been past 5th gear yet. But so far, it's amazing. First, the build quality is very nice. It looks and feels sturdy, and the finish on all the parts looks great (I got a black housing with chrome everything else, the standard options). Also, everything fits exactly like it's supposed to. No problems with mounting the starter and no problems with it mating up to the inner primary. Nothing is off center, and the bolt holes are nice and clean, so no need to re-tap or debur anything. As far as operation, with my upgraded clutch (stock basket with a kevlar extra plate kit), I used to have to blip the throttle to get it into neutral when it was running on the stock 5-speed, but on this one, it just goes into neutral pretty solidly and easily when I am not moving, it's not a fight to get there. So far, I haven't hit a single false neutral anywhere, and I don't think I'll ever accidentally shift into neutral between first and second while moving down the road. The only thing I noticed so far, was that third gear seems to run out a little sooner than stock (previous shift point for 4th gear was around 40 mph, but on this, it's closer to 35 mph, at least on my build), but first gear is longer, which is great and all the other shift points seem the same. On the stock, first gear seemed to be way too much and wound out super quick, so a definite improvement. Customer service was great too, and I didn't have to wait very long at all once I ordered.
