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 factory low steer knuckles
  • Raises drag link and trac bar axle mounting points 2.75 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 2.5 in. of bump stop!
  • JK systems provide increased steering angles, offering an additional 10 percent to align with the stock steering angles of JL/JT models
  • 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.
  • A picture is worth a thousand words, as they say! Please review this item’s photo gallery!

Kit Fits:

*Fits all listed vehicles below, granted they retain the width front differential, or any factory width aftermarket differential that features factory spec. inner C-knuckles.
  • JK Wrangler Unlimited (4-door) - All Models (retaining steering stabilizer shock with D30 or D44 differential)
  • JK Wrangler (2-door) - All Models (retaining steering stabilizer shock with D30 or D44 differential)

RJ-430001-103 Kit

  • Kit is complete with EVERYTHING needed to do the job
  • Designed for use on factory JK D30 and D44 axle housings
  • Can be used on aftermarket axle housings with factory JK inner Cs
  • Kit includes pair of knuckles, bolt-on Currectlync Steering System, trac bar relocation bracket that incorporates a raised steering stabilizer shock mounting location, a corresponding stabilizer shock , plus a JL/JT style forged chromoly organically shaped front
  • JL/JT trac bar allows for maximum up travel potential and/or lower lift height requirements
  • Kit is recommended for use with RockJock’s adjustable front bump stop kit to ensure maximum up-travel, as engineered
  • Engineered for use with 2.5 in. up to 6 in. of lift

Knuckles (included)

  • 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
  • RockJock’s cast 65-45-12 ductile iron 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)

  • is raised 2.75 in.
  • 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 2.5 in. of , 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

Trac Bar (included)

  • Use of the longer JL/JT allows for more up travel potential and/or lower lift height requirements
  • Forged trac bars provide maximum rigidity for added road stability and driving comfort

Bracket Kit (included)

  • relocates the trac bar mounting point up 2.75 in. for corrected front end geometry, improving stability, reducing body roll, and preventing bump steer
  • Bracket 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 adjustable bump stop kit is recommended for ease of achieving the up travel that these components are capable of, as engineered

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: shock be used. The longer JL/JT shock allows increased steering angles, offering an additional 10 percent to align with the stock steering angles of JL/JT models
  • 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
