7-Speed Transmission Gear Set - DD7 kit 17-21 M8

Direct replacement for the Harley-Davidson 6-speed Cruise Drive
Seventh gear allows you to make the most of the torque and power of 96 ci, 103 ci and 110 ci engines through transmission ratio management.
Unlike the original mainshaft which includes 1st to 4th gears, the DD7 is lightweight and incorporates only the small 1st gear, minimising gear change noise.
Shortened first gear and adjusted remaining gears for a smooth and powerful riding experience with continuous acceleration from 1st to 4th gear.
Smooth gear changes are achieved through a new linear retention system with ball bearings, integrated into the machined upper cover.
Ready to install on the bike, no need to modify the crankcase or adjust the gear clearance
Includes seventh main gear, main bearing and main seal to replace the sixth gear.
Includes new main gear bearing and seal, polished cover, cover gasket, side cover gasket, top cover gasket and DD7 self-adhesive emblem for the side cover
Bearing door manufactured from 6061-T6 aluminium with wider bearings and retaining plates instead of standard circlips
12-point ARP screws for door, top cover and original side cover; includes Baker re-cal box and cables
DD7 door bearings are 28% wider than the originals
