Competition U-Joints and U-Bolts

We carry the Spicer brand SDO solid racing U-Joints, which are also used in our racing driveshafts.  By deleting the grease fitting hole, an inherent weak point is eliminated in the “cross” of the U-joint.  Precision machined to very high tolerances to remove vibration causing play.  Note # 285-5-648X is NOT solid.
