JIMS is proud to offer 6-speed overdrive transmission gears made in the U.S.A. by JIMS. Imagine riding down the road at 75 MPH in 5th gear and by shifting into 6th you reduce your engine RPM by almost 500 RPM.’s. It’s possible to have this option with the strength and reliability of JIMS quality gears and shafts. All gears are standard width for performance and strength, with first gear being close ratio 2.94, and the last four being the same ratio as a stock 5-speed. 6th gear goes to .86:1 overdrive. See Additional Information for fitment.
