Differential Yokes
Differential yokes connect the driveshaft to the differential pinion flange, transferring rotational force from the transmission through to the drive axle. Worn or damaged yokes cause vibration, driveline noise, and universal joint failure. Upgrading to a stronger yoke is common on high-horsepower builds, lifted trucks with increased driveshaft angles, and off-road rigs that regularly abuse the drivetrain.Popular Differential Yoke UpgradesHeavy-duty forged steel yokes from Yukon Gear and Spicer are available for Dana 44, Dana 60, Ford 9-inch, GM 8.5, and GM 14-bolt axles. 1350 and 1410 series yokes are popular upgrades over factory 1310 units on trucks running larger tires and lifted suspensions, as they support bigger U-joints with higher torque ratings. Slip yoke eliminators pair with solid front driveshafts on lifted Jeep TJ and XJ builds.How do I match a yoke to my driveshaft?Yokes must match both the differential pinion flange dimension and the U-joint series size used by your ...
