Sonnax T3-3-6081H – 1350 Series Forged 4340 Chromoly Roller Bearing Slip Yoke – 27 Spline

Sonnax T3-3-6081H – 1350 Series Forged 4340 Chromoly Roller Bearing Slip Yoke – 27 Spline

The Sonnax T3-3-6081H is a high-performance forged 4340 chromoly transmission slip yoke specifically designed for transmissions equipped with roller bearing tail housings. Built for high-horsepower and high-torque applications, this slip yoke provides exceptional strength, durability, and reliable driveline performance in demanding racing environments.

Unlike conventional slip yokes designed for bushing-style tail housings, the T3-3-6081H features a through-hardened and tempered barrel engineered to withstand direct contact with transmission tail housing roller bearings. Its precision-machined construction makes it an excellent choice for drag racing, dirt track racing, street performance, and other high-performance applications.

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 specifically designed for transmissions equipped with roller bearing tail housings rather than conventional bushing-style tail housings. Its hardened barrel is engineered to withstand the direct contact and operating loads associated with roller bearings.

Confirm whether your transmission tail housing uses a bushing, single roller bearing, or double roller bearing before purchasing.

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

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