ECGS 4340 DANA 60 U-JOINTD60-U-JOINT-4340
The ECGS U-joint cross is made from 4340 and the caps are 4340. The entire u-joint unit is heat treated and cryo'd for ultimate strength and wear resistance. The u-joint comes with full circle clips and grease fittings that install into the caps. There are no needle bearings in these u-joints. This allows the legs for the caps to be thicker.
