BAKER DRIVETRAIN - direct drive 6 speed builder's kit for Big Twin.

BAKER DRIVETRAIN

Direct Drive 6 Speed Builders Kits for Big Twin

DIRECT DRIVE 6 SPEED BUILDERS KITS FOR BIG TWIN - Baker Drivetrain

Direct Drive means that the 6th gear has a 1:1 ratio (for 1 revolution of the input shaft, the output shaft turns 1 revolution) which is the same as an OE 5 speed.
By including a 28 tooth compensating sprocket and a longer primary drive chain, the overall drive ratio is exactly like a .86:1 overdrive 6th gear but with the 99% mechanical efficiency of a 1:1 ratio drive.
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.
Chrome plated access door.
Fourth, fifth and sixth gear sets have helical cut gear faces to further reduce gear noise.
One piece design of the countershaft and sixth gear eliminates the weak point found in the OE transmission.
Redundant (roller and plunger type) shift drum detents for positive neutral finding.
Anti-overshift inner transmission linkage with improved shape return spring for dependability.
The 28 tooth compensating sprocket yields 14% more starter motor torque to the engine. Made in U.S.A.
