Description
90-4-311-1 — SPL90 Series end yoke with 2.024-inch spline bore, 3.000-inch hub, and BS snap ring retention. Drop-in replacement for SPL90 Series output shafts.
Full Description
Every driveshaft system is only as strong as its weakest yoke. The 90-4-311-1 is a UDS SPL90 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 2.024" spline interface and precision-machined bearing seats, this yoke transfers power cleanly without the slop that kills U-joints prematurely.
Performance-Grade Construction
The SPL90 Series yoke series was developed to handle loads beyond light-duty OEM specifications. The 90-4-311-1 carries the full load rating of the SPL90 Series system, making it appropriate for high-torque applications including turbocharged and supercharged drivetrains, towing configurations, and competition use.
- Full SPL90 Series torque rating -- no derating for special applications
- Precision bearing bores -- eliminate U-joint cap rocking that causes premature wear
- Snap ring style: BS -- positive retention under shock loading
- Hub diameter: 3.000" -- correct registration against diff or transfer case seal

Specifications
Performance fitment requires exact dimensional matching. The 90-4-311-1 is built to the following specs:
Pairing for Maximum Drivetrain Life
The weakest link in any driveshaft assembly determines its service life. Pairing a fresh 90-4-311-1 end yoke with a new SPL90 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 4.625" must be accounted for when calculating driveshaft operating length after suspension lifts or drivetrain swaps.
Part 90-4-311-1 is a UDS product. Universal Driveshafts stocks a complete range of SPL90 Series end yokes, U-joints, and driveshaft components. Contact our technical team for fitment assistance.
