Important Fitment Information
Verify transmission output shaft spline count, slip yoke barrel diameter, U-joint series, and required operating length before ordering.
Important: The Kevko K55STD is a Kevko Racing branded product. Dana Spicer part number 2-3-6081X is used for dimensional reference only. This product is not manufactured or branded by Dana Spicer.
Some transmissions have different output shaft configurations depending on model year, transmission version, and application. Verify measurements rather than relying solely on transmission model.
Proper spline engagement and slip yoke travel must be maintained throughout the suspension's full operating range. The slip yoke must not bottom out in the transmission or lose adequate spline engagement at full suspension extension.
This slip yoke accepts 1310 series U-joints with approximately 1.062" bearing caps and 3.219" overall joint width.
