Roll Pin Counter Shaft

The Winters Roll Pin Counter Shaft (part number 67991) is a precision-engineered component specifically designed for use in transmission counter-shaft assemblies. This compact yet critical part serves as a pivot point, managing rotational forces and maintaining gear alignment under load. It is essential for applications where consistent mesh geometry between paired gears is required.

Manufactured by Winters, a trusted name in performance transmissions, this roll pin is machined to tight tolerances to ensure a proper fit within counter-shaft bores. The roll pin design allows for controlled radial compliance while resisting axial movement, which is crucial in transmission internals. This balance helps to minimize excessive play that can lead to gear noise and premature wear.

Mechanics and transmission builders rely on Winters counter shaft components when assembling or rebuilding performance gearboxes. Proper installation requires careful alignment of the counter shaft within the transmission, ensuring optimal performance in both street and racing applications.
