Proven in rock crawling and rock racing competition by Shannon Campbell, our competition outer axle yokes are constructed of billet 4340 and then heat treated for ultimate strength. The fully bridged design allows these yokes the capablity of over 40 degrees of turning angle. These yokes will accept any standard 35 splined shaft, the stock F-350/F-450 seal and any common 1 ton 1480 style u-joint.
