Baker Drivetrain 7-Speed Gear Set for Harley-Davidson with Part Number DD7-37603

Gear Set - 7-Speed/Transmission - Black

Upgrade your Harley-Davidson with the Baker Drivetrain DD7-37603 7-speed gear set, designed as a direct replacement for the factory 6-speed cruise drive transmission. This innovative gear set enhances your motorcycle's performance by utilizing a 7th gear, allowing for optimal gear ratio management that maximizes torque and power output from 96 ci, 103 ci, and 110 ci engines. Unlike the stock mainshaft, which includes gears 1 through 4, the DD7 features a lightweight design with only the small 1st gear, reducing shift clunk and providing a smoother riding experience. The shortened 1st gear combined with tightened all other gears ensures continuous acceleration from 1st through 4th gear, contributing to a more responsive and powerful ride. The shift smoothness is further improved by a new linear roller ball detent mechanism integrated into the supplied billet top cover, which guarantees precise gear engagement.
Installation is straightforward, as the DD7 set is ready to slide into your bike without requiring case modifications, shimming, or adjustments. The set includes the 7th main drive gear, main drive gear bearing, and main drive seal, allowing you to replace the existing 6th gear setup seamlessly. Additionally, the kit comes with a polished door, door gasket, side cover gasket, top cover gasket, and a self-adhesive side cover emblem, ensuring a complete upgrade. The door bearing housing is manufactured from durable 6061-T6 aluminum with wider bearings and a bearing retainer plate that replaces stock snap rings, providing increased stability and longevity. ARP 12-point bolts secure the door, top cover, and side cover for added strength.
The DD7 door bearings are 28% wider than stock, utilizing an F6F door bearing retainer plate for enhanced durability. The set reuses the stock shifter pawl and includes Baker re-cal box and leads, making it a comprehensive upgrade for your Harley-Davidson transmission. Made in the USA, this gear set offers reliable performance and smooth shifting, transforming your motorcycle's drivetrain for optimal power delivery and riding comfort.
