2-4-1233 End Yoke – Round Bore 1310 Series, 1.500 Bore KEYWAY: 0.375 , Hub Diameter: 2.125

Every driveshaft system is only as strong as its weakest yoke. The 2-4-1233 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 KEYWAY- 0.375" 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 2-4-1233 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: RB -- positive retention under shock loading
• Hub diameter: 2.125" -- correct registration against diff or transfer case seal

Specifications

Performance fitment requires exact dimensional matching. The 2-4-1233 is built to the following specs -- particularly relevant for KEYWAY LOCATION AT 12:

Pairing for Maximum Drivetrain Life

The weakest link in any driveshaft assembly determines its service life. Pairing a fresh 2-4-1233 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 2.562" must be accounted for when calculating driveshaft operating length after suspension lifts or drivetrain swaps.
