RockJock’s Currectlync® modular extreme duty steering system for 2007-2018 Jeep JK Wranglers features 1 5/8″ diameter 4130 chrome moly heat treated steel tubing tie rod and drag link tubes, 1 1/4″ thread forged steel greasable tie rod ends, as well as new steering stabilizer shock bracket and u-bolt kit. The massive tie rod ends thread into the tie rod end body so that they may 1) be replaced without replacing the whole rod end saving cost, 2) the same threaded in tie rod end is used at all 4 points so only one spare would have to be carried, and 3) they may be unscrewed from the rod end bodies and screwed in from the other side if a flipped tie rod and/or drag link was desired. Tie rod and drag link tubes feature wrench flats machined onto them and jam nuts for ease of adjustment. This unit is a direct replacement for the stock parts. No modifications or machining to any part of the vehicle are necessary, and best of all, it’s made in the U.S.A.! NOTES: Flipping the tie rod or drag link would require retapering the tie rod end holes from the top side of the knuckle. Rod end taper is 1.5″ per foot.
