Product Description
Rock Jock High Steer Knuckle Kit | for Stabilizer Shock & JL/JT Track Bar (Wrangler JK 2007-2018)
RockJock's High Steer Knuckle Kit for JK Wrangler and Unlimited vehicles 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 (Dana 30 and 44), this kit replaces the factory knuckles with our cast iron high steer knuckles (RJ-437100-101) that exceed OEM quality and strength. Our knuckles raise both the tie rod and the drag link 2 3/4 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 rig. The new knuckles also feature two adjustable steering stop locations (fore and aft of axle centerline) 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.
Our Currectlync steering included in this kit features our revolutionary high articulation forged chromoly drag link (JK-9704DL-T) that incorporates a unique organic shape with many compound curves, that can only be achieved via forging, resulting in maximum up-travel capabilities. Our tie rod (RJ-432103-101) 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, this kit optimizes the vehicle front suspension geometry via our included a trac bar geometry relocation bracket with a fully integrated steering stabilizer shock mount (RJ-431111-103). The trac bar mounting point portion of the bracket is raised 2 in., to correct geometry, preventing any bump steer as well as a relocated trac bar mounting hole to accept our RJ-9120FJLF that is included in this kit.
Also provided is our high-end, forged chromoly ram assist clamp tie rod clamp (RJ-441001-101) that easily installs onto the 42mm (1 5/8 in.) tie rod tube, allowing for full adjustability.
Our longer RJ-9120FJLF forged chromoly organically shaped JL/JT front trac bar is included in this kit to finish out the optimization of the front suspension geometry provided by this kit.
The use of our RJ-107101-101 fully adjustable front bump stop kit is highly recommended to ensure all components nest together for maximum up-travel, as engineered.
Kit Includes:
- One (1) pair of knuckles
- One (1) drag link
- One (1) tie rod
- One (1) front track bar
- One (1) track bar relocation and stabilizer shock mount axle bracket
- Stabilizer shock tie rod clamp
- Necessary hardware
- Installation instructions
- For use on any factory JK front differential (Dana 30 or 44), or any aftermarket JK replacement axle that features factory specification inner C-knuckles and up to 3 1/2 in. diameter axle tubes.
- Retains factory unit bearings, axle shafts, ball joints, steering stop bolts and brakes with dust shields.
- Trac bar relocation / ram assist axle bracket kit provides new sway bar link mounting holes that are raised 2 1/8 in. higher than stock (sway bar link lengths must be adjusted to accommodate this).
- Intended to be used with a minimum of a 17 in. diameter wheel and up to a 6 in. wheel backspacing.
- A minimum bump stop extension is mandatory to keep components from crashing under full articulation range conditions. See our bump stop options here.
- This kit requires the use of either a factory JL/JT stabilizer shock or, specifically, Bilstein’s B8 5100 series stock replacement shock, part number: 33-292984 shock be used.
Notes:
** This geometry optimized kit requires the use of the supplied, longer RJ-9120FJLF JL/JT front Trac Bar
*** To take full advantage of the up-travel that this kit is capable of, we recommend the use of our RJ-107101-101 adjustable bump stop kit.
**** This kit requires the use of either a factory JL/JT stabilizer shock or, specifically, Bilstein’s B8 5100 series stock replacement shock, part number: 33-292984 shock be used.
