Features of Shifter Yokes, Shifter Shoes & Studs

Should you choose to fabricate your own shifting mechanism, CJM's Manual Shifter Yokes will include a pair of our shifter shoes in the design. Our shifter shoes are fabricated from a slow-wearing material which is adaptable to any speed, ensuring they are suitable to your clutch's operation. When assembled, shoes should be attached directly opposite each other and allowed to float in the groove of the clutch shifting sleeve.

Manual shifter yokes are just one of the many power transmission parts Carlyle Johnson supplies. Customers often choose us as their single source for clutch and brakes units and parts. If you are custom-building a component, contact us regarding additional transmission elements including housings, gears and shafts.
