The Currie Currectlync® heavy duty tie rod and drag link system for TJ, LJ, XJ, and MJ vehicles features, a 1 ¼" diameter forged alloy drag link, and 1 ¼" solid alloy steel tie rod bar that is bored and threaded on the ends. All 7/8" thread tie rod ends with boots are included as well as the Currie heavy duty steering stabilizer bracket. This unit is a direct replacement for the stock parts. No modifications or machining to any part of the vehicle is necessary. This unit is rated at 200% stronger than the stock components. NOTE: This unit is designed to be used on vehicles with 4" of lift. It can be used on vehicles with less lift, but the vehicle must have a minimum of a 2" bump stop (over stock). Also, on vehicles with no lift, 2 of the tie rod ends may need be trimmed to achieve proper adjustment.
