BAKER Spline Information
Our 4-Speed and 6-INTO-4 transmission sprockets and pulleys are based off of the early 5-Speed 6 tooth straight spline from 1980-84. This spline is larger than a stock 4-Speed style spline. Why did we adopted this larger spline? Using a larger spline gave us the ability to run caged needle bearings inside of the main drive gear. Stock 4-Speed main drive gears use a brass bushing instead of bearings. This bushing wears over time and causes a major transmission leak.
