Q: WHY RockJock High Steer Knuckle Kits? A: Here's a whole list of reasons!
More than just a pair of knuckles, the only High Steer Kits on the market that are Complete!
These are bolt-on kits designed specifically for the JL/JT/JK vehicle platforms, engineered to optimize performance and available with both steering damper and ram assist options
THIS IS NOT a flip kit! Kits feature new knuckle castings with elevated steering arms - making them the highest High Steer solution available on the market!
Cast, 65-45-12 ductile iron knuckles replace the unreliable stock aluminum knuckles
Raises drag link and trac bar axle mounting points 2.50 in., correcting front end geometry to enhance stability, reduce body roll, and prevent bump steer
Preserves correct Ackermann geometry for safe and reliable on-road handling across all speeds and conditions, including highway driving, towing, and heavy loads
Lifts the tie rod by 2.75 in., elevating it above the rocks and enhancing ground clearance for all steering components
While most flip kits require a minimum of 3.0 in. of bump stop, the RockJock High Steer incorporates a dip in both the drag link and tie rod to optimize up travel potential, requiring only 2.2 in. (gas), 1.1 in. (diesel) and .188 in. (392) of bump stop!
CAD-based packaging using our forged, organically shaped trac bar and drag link prevents components from making premature contact with the frame, enabling greater upward travel than stock, even with lifts as low as 3 in.
Kit Fits:
Fits all listed vehicles below, granted they retain the factory, narrow width (Sport/Sahara) front differential, or any aftermarket differential that features factory spec. inner C-knuckles.
- JL Wrangler Unlimited (4-door) - Sport/Sahara Models (retaining steering stabilizer shock)
- JL Wrangler (2-door) - Sport/Sahara (retaining steering stabilizer shock)
- JT Gladiator - Sport Models (retaining steering stabilizer shock)
RJ-440001-103 Kit
Kit is complete with Everything needed to do the job
Designed for use on the narrow width factory JL/JT axles (found in Sports, Saharas, etc.)
Can be used on aftermarket axle housings with factory JL/JT inner Cs
Kit includes pair of knuckles, bolt-on Currectlync Steering System, that incorporates a raised steering stabilizer shock mounting location, plus a corresponding stabilizer shock tie-rod clamp
Kit is recommended for use with RockJock's RJ-9120FJLF forged chromoly organically shaped front trac bar and RJ-107101-101 adjustable front bump stop kit to ensure all components nest together for maximum up-travel, as engineered
Engineered for use with 2.5 in. up to 6 in. of lift
Knuckles (included)
Knuckles 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
Allows for ALL factory outer components to be retained, including ball joints, unit bearings, outer axles, brakes and dust shields
OEM JL/JT aluminum knuckles are replaced with RockJock's cast 65-45-12 ductile iron knuckles. The stock aluminum knuckles often fail at the taper and ball joint press holes over time. RockJock knuckles exceed OEM quality and strength
NOT a flip kit! Knuckles feature longer, raised steering arms that push the tie rod outward, away from the axle slightly, allowing for tighter steering angle over that of stock and 1 ton axles
RH Knuckle features a rearward tipping of the upper, tapered drag link mounting hole to help the rod end head clear 17 in. wheels (mandatory), with up to stock offset/backspacing of ET=44.45
Steering (included)
Drag Link is raised 2.50 in.
Tie Rod is raised 2.75 in.
Raising of steering rods puts them back to stock geometry after vehicle is lifted restoring factory steering geometry for improved drivability and overall road comfort on a lifted rig
Raising of steering rods puts them out of harm's way
Dip in tie rod and dip in drag link allow for maximum up travel, requiring only 2.2 in. (gas), 1.1 in. (diesel) and .188 in. (392) of bump stop, as opposed to a 3.0 in. bump stop on most competitor kits
Vehicles already equipped with RockJock steering (with forged drag link) can reuse their steering
Bracket Kit (included)
Bracket kit relocates the trac bar mounting point up 2.50 in. for corrected front end geometry, improving stability, reducing body roll, and preventing bump steer
Bracket kit relocates the axle end of the steering stabilizer shock dramatically higher to correct it's geometry for this high steer application
Relocated shock height protects the shock from rock strikes
Optional Equipment
The use of RockJock's forged, RJ-9120FJLF forged chromoly organically shaped trac bar and RJ-107100-101 adjustable bump stop kit are recommended for ease of achieving the up travel that these components are capable of, as engineered (vehicles already equipped with RockJock forged, organically shaped trac bar can reuse their trac bar)
Steering Stabilizer Shock Notes:
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
Twin tube and thru-rod stabilizer shocks will intersect with other components and are not for use with this system
Diff Cover Notes:
With regards to differential cover clearance, this system was engineered around an OEM cover. Aftermarket diff covers may need to be clearanced to allow the stabilizer shock tie rod bracket to clear. However, be aware, some diff covers may not work at all
Warranty 2-year limited warranty
