Baker DD7 Direct Drive 7-Speed Transmission Gear Set Kit


  • Direct replacement of the Cruise Drive Harley-Davidson factory 6-speed transmission
  • The 7th gear enables the motorcycle to make full use, by the way of gear ratio management, of the torque and power put out by the MoCo's big V-twin enginer
  • Unlike the stock mainshaft which includes 1st through 4th gears, the DD7 is lightweight and only includes the small 1st gear, minimizing shift clunk
  • Features a shortened 1st gear and tightened all other gears for a smooth and powerful riding experience with continuous acceleration from 1st to 4th gear
  • Shift smoothness is achieved by use of a new linear roller ball detent which is part of the supplied billet top cover
  • Comes ready to slide in the bike, no case modifications, shimming of the gear set or adjustments required
  • 7th main drive gear, main drive gear bearing, main drive seal are all included to replace 6th main
  • Stainless steel ARP 12-point head bolts for door, top cover, stock side cover, Baker re-cal box and leads all included
  • Reuses stock shifter pawl
  • Includes new main drive gear bearing and seal, polished door, door gasket, side cover gasket, top cover gasket and self-adhesive DD7 side cover emblem
  • Utilizes F6F door bearing retainer plate
  • DD7 door bearings are 28% wider than stock
  • Backed by a 5 year, 50,000 mile limited warranty
  • Made in the USA
