What's My Rear Attachment?
QA1 currently offers the U-joint and flange yoke series listed below. Each table below lists their dimensions in reference to the drawing figures. We are always adding more options to our list, so please contact us at 800.721.7761 if you don't see what you're looking for.
U-Joint Series
There are many U-joint sizes to accommodate many different applications and power. The max torque ratings of the driveshafts are determined by the U-joint selected. QA1 choses the best materials for our driveshafts, which is why we use Spicer Life Series U-joints as a standard option. They provide durability and high torque capacity and are sealed for maximum strength and no maintenance.
