Description: BAKER Drivetrain DD6 direct drive six speed left side drive complete transmission for 1990-1999 Evolution Softail Harley-Davidson Motorcycles; raw finish The BAKER DD6 is the ultimate transmission for serious touring, bagger, Softail, or Dyna riders. The ones who really put the miles on appreciate the silent smoothness with the helical highway gears and direct drive engineering. All steps have been taken to dampen vibration so you, your motor, and the rest of the bike can go the long haul for years to come. Owning an American made BAKER DD6 will give you peace of mind in your travels. You’ll know that you have the premium drivetrain transmission that strictly is built to endure. Fits 1990-1999 Evolution Softail. Raw finish case with chrome accents. Bearing Door Type: All DD6 bearing doors have the same outer profile as a stock 5-speed, so exhaust brackets, torque arms, et cetera, 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. Backed by a 5 year manufacturer's limited warranty from BAKER Drivetrain. The BAKER DD6 combines 3 technical approaches to achieve the most advanced transmission gearset design available for your Big Twin with minimal compromise. First, 1st through 3rd gears are straight cut (spur) for strength during maximum acceleration with no parasitic axial thrust. Secondly, 4th and 5th gears are automotive style helical gears for quiet and smooth operation as highway speed approaches. Lastly, 6th gear is direct drive which means there is no underdrive or overdrive in top gear which translates into 99% efficiency for minimum parasitic loss, minimum wear and tear, and maximum fuel efficiency. But BAKER didn’t focus solely on the gearset; BAKER made this sucker shift like glass. The sequential motion of the hard chrome plated forks is controlled by a fixed spindle radial ball bearing mounted shift drum. Hard chrome guarantees long fork life with minimal imposed friction on the fork groove of the gear. The fixed spindle drum design eliminates any chance of binding or imposed friction about the axis of drum rotation. Drum rotation is controlled by a roller detent and actuated by a BAKER shift pawl with a anti-overshift feature. To make finding neutral an easy chore, BAKER mounted a redundant detent on the left side pillow block. We’re just going to get straight to the point: all 1999-2006 baggers ought to have a BAKER DD6 transmission. It’s specifically designed with these bikes in mind. Harley acknowledged the need for a 6-Speed with the release of their Cruise Drive a few years ago. There are millions of bikes of this vintage on the fast-moving modern highways that can have a brand new existence with the installation of the BAKER Direct Drive 6-Speed. The BAKER DD6 is finessed for touring model bikes, especially for the later Twin Cam powertrains, as the DD6 mitigates noise amplified in the hollow space between the motor and the tranny. It is the perfect blend of gear ratio, gear type, noise reduction advancements, shift system technology, bearing upgrades, and ease of installation. Since the release of the BAKER DD6 in 2003, there have been thousands of satisfied customers world-wide with American touring Big Twins who will attest that it is the premium transmission of choice. What you get with the DD6: Pre-assembled gearset, ready to easily install. Install on a Saturday and ride on Sunday! Helical 4th, 5th and 6th, for a smooth and quiet ride in your cruising gears. 28-tooth compensating sprocket included. Necessary to maintain 1st - 5th stock gearing. Note: For better get-up-and-go, a 27-tooth compensating sprocket is available as a no-cost option. Overdrive is obtained through the primary, so this ratio reduces strain on the starter with 14% more torque. The lower RPM in the primary drive reduces resonant noise found in Twin Cam transmission cases at higher primary RPM’s. Roller detent shift drum, with fixed spindle, eliminates shimming and misalignment. Finding neutral is very easy with a redundant neutral detent. It also makes installation simpler and less risky to screw up. Inner primary race/spacer included. 3-point contact shift forks, hard chrome plated for extended life. Shifter pawl assembly with improved geometry for a perfect response. Includes a built in overshift protection for smooth, precise shifting. Primary chain included with kit. 1st, 2nd, and 3rd gears are straight cut to prevent lateral tension in those high torque, short-used gear ranges. Stiff, precise billet aluminum bearing door that offers more bearing-protecting lateral rigidity than any other helical gearset available. Proprietary fork rod made to bearing grade specifications which eliminates hang-ups. What you get from the DD6: The feel of a new bike: The end-all, proven and perfected helical gear design for smooth and silent operation in the cruising gears (4th-6th). The option to ride hard: Conventional gear shape for strength in the high-torque ranges (1st-3rd) so you can get on it and wick that throttle! Optimized use of horsepower: 99% efficient in 6th gear with a 400-500 rpm reduction depending on application. Certain and positive shifting: Fixed spindle shift drum for smooth, low inertia, drum indexing. Anti-overshift ratchet pawl prevents mis-shifts. Confidence in the ride: Full width BAKER ground gears finished on diamondcoated tooling are strong and dependable. An American soul: It’s made in the USA! It’s designed here too. You’ll have a leg up on those riders with cheap, foreign junk. Easy installation: No grinding to the case required (with very, very rare exceptions). Many competitors’ 6-speed builder’s kits do require grinding. No exhaust clearance issues: The trap door is the same width as stock. ALSO AVAILABLE: BAKER Builder's Kits come fully assembled and ready to install into your existing transmission case with no modifications, shimming, or adjustments required.
