Important Fitment Information
Verify transmission output shaft spline count, journal diameter, U-joint series, and centerline-to-end length before ordering. Transmission output shaft configurations may vary by application.
Important: The Kevko K9CM is designed for racing transmissions that have been machined to accept a 9" slip yoke. Transmission output shaft modification may be required to provide proper clearance and prevent the slip yoke from bottoming out.
Consult a qualified transmission builder or driveline specialist to verify proper fitment, spline engagement, and operating clearance before installation.
