Sonnax T3-3-5551HP – 1350 Series Forged Chromoly Slip Yoke – 32 Spline – 7.940" Length

Sonnax T3-3-5551HP – 1350 Series Forged Chromoly Slip Yoke – 32 Spline

The Sonnax T3-3-5551HP is a high-performance, extended-length forged chromoly transmission slip yoke designed for increased strength, durability, and reliable driveline performance in demanding applications. Built to handle high horsepower and torque, this slip yoke is an excellent upgrade over factory-style components for street performance, drag racing, dirt track racing, and other high-performance applications.

Featuring a 32-spline configuration, 1.886" journal diameter, and 7.940" centerline-to-end length, this slip yoke provides additional length for applications requiring increased driveline engagement. Its 0.220" counterbore accommodates compatible transmission and transfer case output shaft configurations.

Important Fitment Information

Verify transmission or transfer case output shaft spline count, journal diameter, U-joint series, counterbore requirements, and centerline-to-end length before ordering. Output shaft configurations may vary by application.

Important: This slip yoke features a 0.220" counterbore. Verify that the counterbore design is compatible with your transmission or transfer case output shaft before installation.

Some transmission output shafts may have missing spline positions. Include any missing spline positions when determining the correct spline count.

Extended-length slip yokes require proper driveshaft clearance and spline engagement throughout the suspension's full range of travel. Verify that the slip yoke does not bottom out under suspension compression.

Consult a qualified transmission builder or driveline specialist to verify proper fitment and operating clearance before installation.
