U-Joint 1350, 3-5/8'' spread X 1-3/16'' cap

This is a Spicer brand solid SDO racing U-Joint, which is 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.
