Sprint Car MPD Racing U-Joint Spring

This spring is designed to go in the front u-joint to hold pressure on the driveshaft. The spring will fit in any u-joint on the market. Simply place the spring with some grease inside the u-joint when you’re installing your engine.

NOTE: Our Winters J-joint  940-2320 comes with this spring built in with a retainer clip to keep it from falling out.
