3104-30 – End Yoke – 1.312″ Splines dia – 1.940″ Hub Dia – 30 Spline

Every driveshaft system is only as strong as its weakest yoke. The 3104-30 is a UDS 1310 Series end yoke built to handle the torsional demands of performance applications -- from high-horsepower street builds to off-road rigs that flex the suspension to its limits. With a 1.312" spline interface and precision-machined bearing seats, this yoke transfers power cleanly without the slop that kills U-joints prematurely.

Performance-Grade Construction

The 1310 Series yoke series was developed to handle loads beyond light-duty OEM specifications. The 3104-30 carries the full load rating of the 1310 Series system, making it appropriate for high-torque applications including turbocharged and supercharged drivetrains, towing configurations, and competition use.

• Full 1310 Series torque rating -- no derating for special applications
• Precision bearing bores -- eliminate U-joint cap rocking that causes premature wear
• Snap ring style: UB -- positive retention under shock loading
• Hub diameter: 1.940" -- correct registration against diff or transfer case seal

Specifications

Performance fitment requires exact dimensional matching. The 3104-30 is built to the following specs -- particularly relevant for GM 8.5:

Pairing for Maximum Drivetrain Life

The weakest link in any driveshaft assembly determines its service life. Pairing a fresh 3104-30 end yoke with a new 1310 Series U-joint and a properly balanced driveshaft eliminates the three most common failure points. For high-horsepower builds, also inspect the driveshaft tube for straightness and the slip yoke for wear -- replacing a yoke without addressing these components leaves the system vulnerable to the same vibration-induced failure.

Center-to-end measurement of 3.160" must be accounted for when calculating driveshaft operating length after suspension lifts or drivetrain swaps.
