BAKER 5 & 6 SPEED TRANSMISSION ASSEMBLIES FOR SOFTAIL

CHROME AND POLISHED
All gears are finish ground on diamond coated tooling after heat treating to produce a super fine surface for holding exact tolerances and eliminating gear mesh noise. All gear dogs have lead-in ramps for positive gear engagements. To eliminate a weak area normally associated with the 5 speed transmission, Baker has incorporated the countershaft and the countershaft's top gear into one piece. Redundant shift drum detents (roller type & plunger type for positive neutral finding). Anti-Overshift inner transmission shift linkage with improved shape return spring for dependability. Polished case with chrome plated top cover and side cover.
Lightened steel pulley with 32 teeth. 2.94:1 close ratio first gear adds approximately 5 miles per hour of usable first gear.
The 6 speed has a .86:1 ratio top gear and will reduce RPM by approximately 475. These transmissions include a single wire type neutral switch designed for 1984/1997 Softail models and can be used with an electronic speedometer sensor.
The 5 speed version is best suited for stock through moderately modified engines.
The 6 speed version is best suited for large displacement engines.
A Manufacturer's Statement of Origin is included.

POWERHOUSE 6 SPEED TRANSMISSION ASSEMBLY FOR SOFTAIL 1990/1999

If you have ever been cruising on the highway and tried to upshift into top gear just to find out your transmission is already in fifth gear, then that is all the proof you should require that you need a 6 speed transmission. Not only will this complete transmission assembly reduce vibration at highway speed, it will also improve fuel mileage. At 75 miles per hour, the .86:1 overdrive ratio will produce a 475 RPM reduction when shifting from fifth gear. A 2.94:1 close ratio first gear will add approximately 5 MPH of useable first gear. The second, third, and fourth gear ratios remain the same as OE. Fits Softail models 1990/1999.
