This assembly was made to cure the many u-joint failures in the last few years. Tighter tolerances keep the u-joint centered in the base and yoke with no slop.U-bolts securely retain joint in the base and yoke eliminating any possible c-clip failure. Complete assembly machined from 7075 billet aluminum. Heavy-duty joint never needs to be greased. Available with 16 or 32-spline yoke.
