RockJock High Steer Knuckles for all JK Wrangler and Unlimited vehicles are a game changer! These new knuckles raise both the tie rod and drag link 2 3/4 in. as well as pushing the tie rod outward, away from the axle slightly, allowing for tighter (JL/JT) steering angle over that of stock JK and 1 ton axles.
For use on factory axles or axles that retain factory inner C-knuckles, our new high steer knuckles are intended for use with in conjunction with all of our other high steer components, to give you a package that provides everything necessary to accommodate the higher steering location, adjust all geometry points and allow you to easily install a hydraulic assist steering ram, or to reinstall a stabilizer shock!
Knuckles are manufactured to greater than OEM standards in every way. Features include premium iron castings, gloss black finish and precise machining for a component that installs just like factory. Additional adjustable steering stops ahead of the axle have been added, giving you firm, fore and aft steering stops on both wheels at all times, easing strain on other components.
For best results, it is highly recommended that these knuckles be used in conjunction with one of our knuckle kits that include all of the other components to make this installation easy.
Our RJ-430000-101 kit includes a forged, high articulation Drag Link, a 42mm chromoly Tie Rod, a JL/JT Trac Bar as well as the bracket and clamp kits to allow you to install a hydraulic assist steering ram.
We also offer our RJ-430001-101 and RJ-430001-101 kits that include the same Drag Link and Tie Rod, as well as the bracket and clamp kits to allow you to reinstall your steering stabilizer shock at a much higher, protected height.
Kits that retain the steering stabilizer shock are available with or without our longer RJ-9120FJLF forged, organically shaped JL/JT front trac bar (for 5/8 in. higher articulation!).
Use of our RJ-107101-101 adjustable front bump stop kit is strongly encouraged to allow for maximum up-travel, as engineered.

Intended to be used with a minimum of a 17 in. diameter wheel and up to a 6 in. wheel backspacing.
A minimum of a 2.2 in. bump stop extension is mandatory to keep components from crashing under full articulation range conditions. See our RJ-107101-101 adjustable front bump stop kit for an easy to use solution.
Notes:
For optimum performance of these knuckles, we recommend purchasing them in one of our kits that provide the balance of the components for ease of use. See our kits: RJ-430000-101, RJ-430001-101 and RJ-430001-103.
These knuckles were designed in conjunction with and intended for use with our JK-9704 steering system.
These knuckles may or may not work with stock or other aftermarket tie rods and drag links - we have not done that testing!
