Rock Jock High Steer Knuckle Kits for all Jeep JL and JT models is a game changer, packed with features that improve the off-road capabilities, as well as the on-road drivability of your vehicle! Intended for use on factory axles, these kits replace the inferior factory aluminum knuckles with cast iron high steer knuckles that exceed OEM quality and strength. They raise the tie rod 2 3/4 in. and the drag link 2 1/2 in., moving the rods out of the way of rocks and helping to restore factory steering geometry for improved drivability and overall road comfort on a lifted Jeep. The new knuckles also feature two adjustable steering stop locations for full lock-to-lock adjustability which helps ease the strain on steering components at full lock. Stock ball joints, unit bearings, axles, brakes and dust shields are all retained. Rock Jock's Currectlync steering included in these kits features revolutionary high articulation forged chromoly drag link that incorporates a unique organic shape with many compound curves—which can only be achieved via forging, resulting in maximum up-travel capabilities. The tie rod is a 42mm (1 5/8 in.) diameter chromoly tube. All Currectlync steering ends are forged steel and comparable in size to those found on modern 1-ton trucks. Given the dramatic geometry changes vehicle lifts impose, the kits include a trac bar geometry relocation bracket with a fully integrated: a) steering stabilizer shock mount, OR b) ram assist steering mount (depending on the kit you order). The trac bar mounting point is raised 2 1/2 in., to correct geometry, preventing any bump steer. * a) The steering stabilizer shock mounting point portion of the bracket moves the shock up and behind the new tie rod location, far from its vulnerable stock location. OR.... * b) The ram assist mount portion of the bracket provides an easy bolt-up anchor point for your hydraulic assist ram, as well as a lower skid plate, incorporated into the bracket, to protect the ram from rocks. Kits Include: * Left side high steer steering knuckle * Right side high steer steering knuckle * Currectlync Drag Link * Currectlync Tie Rod * Trac bar relocation and ram mount axle bracket -OR- Trac bar relocation and stabilizer shock mount axle bracket (depending on kit) * Stabilizer shock tie rod clamp -OR- Ram assist tie rod clamp (depending on kit chosen)
