Features include 1.3 in. diameter solid forged steel construction, flipped end for high mounting, larger forged, greasable rod ends, premium jam nuts and adjuster, the flipped drag link’s tapered sleeve and the system is painted black, so it's ready for install right out of the box! This easy to install kit only requires drilling of the one hole, no other modifications or machining to any part of the vehicle are necessary! On an entirely separate note, if you happen to be overseas and working with a right hand drive vehicle – this drag link will bolt directly onto a RHD vehicle in the RHD vehicle’s stock configuration. You would then discard the tapered sleeve that comes in this kit.
