Keep torque flowing smoothly from the transmission to the axle with the Spicer Drive Shaft Slip Yoke 3-3-6701X (also written 336701X) from Dana Spicer Chassis. The slip yoke splines onto the driveshaft/output shaft and slides in and out to accommodate the change in driveshaft length as the suspension travels, transmitting torque while allowing that fore-and-aft movement. Depending on the application, this yoke is cataloged for the FRONT, REAR, and REAR DRIVESHAFT AT SUPPORT BEARING positions — confirm the correct position for your vehicle in the Buyer's Guide.
