DD5: Direct Drive 5-Speed Complete Transmission

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
Benefits
  • Handles over 200 ft/lbs of torque (more than stock)
  • Easier to find neutral
  • Smoother shifting
  • Longer lasting components
    • 1987-89 Softail, FXR, FLT-FLH
    • 1990-06 Softail, FXR
    • 1990-92 FLT-FLH
    • 1991-05 Dyna
    • 1993-06 FLT-FLH

     

      Bearing Door Type: 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.

      Mainshaft: The Splined mainshaft comes standard on the DD5 Builder’s Kit. A +.800″ mainshaft and pulley for wide tire applications is available upon request, additional costs may apply. To order the mainshaft and pulley for the wide tire applications, please contact us through the website chat, email us at info@bakerdrivetrain.com, or call us Monday-Friday 8AM-7PM EST/EDT and Saturday 10AM-3PM EST/EDT at 517-339-3835.

      1st Gear Ratio: The 2.94 1st gear ratio is a good all around ratio. The optional 3.24 1st gear is recommended for heavy GVW applications. The R-Ratio 2.82 1st gear is recommended for light hot rods.

      2nd Gear Ratio: We recommend a 2.21 2nd gear ratio for use with the 2.94 and 3.24 1st gear ratios. The 2.08 2nd gear is normally paired with the 2.82 1st gear for racing applications. If you would like a personalized 2nd gear pairing, please contact us through the website chat, email us at info@bakerdrivetrain.com, or call us Monday-Friday 8AM-7PM EST/EDT and Saturday 10AM-3PM EST/EDT at 517-339-3835.

      Bearing Door

      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.

       

      Redundant Neutral System

      Shift System
      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

      Gearset
      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.

      Ratios

      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.

      BAKER Case vs. Aftermarket

      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. 

      Recalibration Box PN 95E-56B

      Special Note

      • Speedo recalibration unit is required for electric speed sensor applications; PN 95E-56A.
      • PN 555-56L-A is required for 2000-06 Softail’s, 2001-06 FL/FLT and 2001-05 Dyna
      • A +.800″ mainshaft and pulley for wide tire applications are available upon request, additional costs may apply.

      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).
