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: This slip yoke is intended for compatible conventional transmission tail housings. If your transmission uses a roller bearing tail housing, Sonnax offers a specifically designed hardened roller bearing version, part number T3-3-6081H.
Some transmission output shafts may have missing spline positions. Include any missing spline positions when determining the correct spline count.
Check whether your transmission tail housing uses a bushing or roller bearing and confirm compatibility with the slip yoke's journal diameter and design.
Consult a qualified transmission builder or driveline specialist to verify proper fitment, spline engagement, and operating clearance before installation.
