ZODIAC'S 6 SPEED CONVERSION FOR SOFTAIL AND DYNA 5 SPEED TRANSMISSIONS

The biggest disadvantage of the stock 5 Speed transmission might be the 1 to 1 gear ratio in fifth gear, resulting in high engine RPM when cruising at high speed. O.K, you can reduce this by changing the final drive ratio, but this will also reduce acceleration. With the new Zodiac Six speed you will have the 1 to 1 gear ratio in 5th gear but 1 to 0,86 ratio in 6th, reducing engine speed with as much as 14%. There are other 6 Speed conversions on the market, but not as economically priced nor have the quality in engineering and CAD/CAM design as the Zodiac Six. These precision parts are CNC manufactured by one of the worlds leading automotive transmission factories. All gears have a smooth tooth surface that guarantees a noiseless and trouble free transmission for tens of thousands of miles.

The Zodiac Six fits all 5 Speed Dyna transmissions from 1991 thru 1998, and Softail transmissions from 1986 thru 2006 when used in combination with a 1990 to present clutch. Available as a conversion kit, a builders kit and as a complete transmission. The Conversion Kit contains main shaft, counter shaft and 6th gear combination, shifter drum, a pair of pillow blocks, complete shifter drum lock mechanism, right hand side center shifter fork, auxiliary shifter fork with shift axle and shifter shaft support, shift locking system, clutch rod, Billet aluminum trap door with bearing lock plate, main shaft 1st, 3rd, 4th and 6th gear, counter shaft 1st, 3rd, and 4th gear, trap door speedo plug with O-ring, and all required hardware, as well as comprehensive instructions how to install the Overdrive Conversion Kit into a Softail transmission, re-using some parts of your own transmission. When you do not want to re-use these parts or when you have a pre-1990 transmission you may want to order one of our Builders Kits. Builder's kits are also available in 25, 45mm or 55mm offset. The offset kits come complete with all parts to offset the primary, such as spacers, crankshaft extension and crankshaft extension nut. Except for the transmission housing with seals and bearing, the end cover with clutch mechanism, the top cover nor any part bolted to the outside, the builders kit contains all parts to build a complete new transmission. For those starting from scratch we also have complete and ready-to-install 6 Speed transmissions available. These can be used with or without electronic speedo pick up as they come with a billet aluminum plug to plug off the pick up hole in the trap door when using a front or rear wheel driven speedo.

What the difference is:

•Gears from 1st thru 5th speed are exactly the same width as stock gears
•Gears and shafts made from High Stress 20CrMnT gear steel
•Gears and shafts tempered and stress released to a core hardness of 35 to 45 Rockwell and a surface hardness of 58 to 60 Rockwell
•Six speed counter shaft gear is a one-piece construction with the shaft
•Fat Billet Aluminum trap door that enables the installation of the extra pair of gears
•Precision machined shifter drum with oversized needle bearing
•State of the art shift locking mechanism for precise and positive shifting
•Un-compromised price to quality ratio
•Also available with 25mm, 45mm or 55mm extended main shaft for offset applications
•5 year or 100,000 KM warranty on material failure

All gaskets, seals, and o-rings are the same as for stock 5 Speed transmissions
