Steel on steel bearings provide exceptional ball joint wear resistance and robustness. Large 1 1/4 inch rolled threads at tie rod adjuster and draglink ends provide significantly increased strength over the original equipment threads. Designed with right-hand and left-hand threads for quick and easy adjustment when installed on the vehicle. Unique Reverse Pin technology on the passenger-side ends prevents our linkage from unwanted flopping/rocking. This technology is built into the socket unlike the weak external supports on some competitor linkages.
