6.5-4-4631 – End Yoke – 1810 Series – 2.794″ Splines Dia – 54 Spline

Finding the right end yoke starts with matching the output shaft -- and 6.5-4-4631 is engineered specifically for 1810 Series driveline applications (HUB DIAMETER NOT GROUND). This UDS end yoke connects your transmission or transfer case output to the driveshaft with dimensional precision that eliminates slop and premature wear.

Dimensional Specifications

Before ordering any end yoke, you must verify the output shaft's spline count and diameter. The 6.5-4-4631 is built around a 2.794-inch spline diameter, 54-spline interface with BP retention. The hub measures 0.000" in diameter, and the center-of-U-joint to end distance is 5.652" -- confirming fit with your specific driveshaft length.

Engineering and Material Quality

Every UDS end yoke in the 1810 Series lineup is forged or precision-machined from high-grade steel to withstand the torsional and bending loads of real-world drivetrain operation. Yoke ears are machined to consistent bearing cup bore tolerances so U-joint caps seat without rocking, preventing the micro-movement that leads to premature joint failure.

• Consistent bearing bore dimensions for tight U-joint fit
• Designed to OEM companion flange specifications
• Through hole ID of 2.750" provides clearance for speedometer cables or internal shafts where applicable
• Compatible with standard 1810 Series U-joint caps

Installation Guidance

Installation requires that the output shaft splines are clean and free of corrosion. Apply a light coat of assembly lube to the splines before pressing the yoke into position. Torque the retaining nut to OEM specification -- do not reuse stretch bolts or damaged snap rings. If the snap ring style is BP, confirm that the groove in the output shaft matches this style before installation.

Always balance the driveshaft assembly after replacing end yokes on vehicles driven above 55 mph to prevent vibration.
