- Creeper U-joint with added center material
- Four install clips included
- Zerk grease fitting included
- Universal fit
Choosing a U-joint type
Joints in a driveline are chosen for the loads they will see. A joint with added material in the center section aims to handle higher torque than a standard part, which can matter for larger tires, heavier loads or aggressive low range use. Matching the joint to the way the vehicle is driven is the simplest way to plan a driveline build.
Whatever joint is chosen, the yoke, flange and clips should be inspected together. Mixing a stronger joint with worn yokes can leave the weakest point elsewhere in the driveline. Keep a record of when the joint was installed and greased so service intervals are easy to track.
- Match the joint to the way you drive
- Inspect yokes and flanges with the joint
- Keep service dates for the driveline
- Grease the joint after each installation
