The RockJock High Steer Knuckles for all JL Wrangler and JT Gladiator models are a game changer! Simply installing these knuckles raises your tie rod 2 3/4 in. and your drag link 2 1/2 in.!

These knuckles, for use on factory axles or axles that retain factory inner C-knuckles, are intended for use with our other high steer components, to give you a package that provides all the necessary components to accommodate the higher steering location, adjust all geometry points and allow you to easily install a hydraulic assist steering ram, or to reinstall your stabilizer shock!
Our 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. Additionally, we've provided extra threaded steering stop bolt holes ahead of the axle to allow for a second set of stops to be added, giving you firm steering lock 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-440000-101 kit includes our forged, high articulation Drag Link, our 42mm chromoly Tie Rod, as well as the bracket and clamp kits to allow you to install a hydraulic assist steering ram. We also offer our RJ-440001-101 kit that includes 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.
Additionally, we recommend the use of our RJ-9120FJLF forged, organically shaped front trac bar, so that all components nest together for maximum up travel as engineered.

We disclaim any express or implied warranties, including, without limitation, implied warranties of merchantability, condition of any kind and fitness for a particular purpose. Our products may be subject to an infinite variety of conditions due to the manner in which they are used, serviced and/or installed. Purchasers and users of such products rely upon their own judgment as to the suitable use, selection, service, and installation of such products. This warranty does not cover damage caused by or facilitated by failure of non-RockJock components. This warranty does not extend to, and RockJock shall not be liable for, any agreements or representations made by dealers or resellers of RockJock products beyond what is stated here.

Because all parts which we sell are intended for use in heavy duty applications, it is not possible to warranty or guarantee the performance of any items under all circumstances. Each warranty represents the sole and exclusive remedy for any product defect or failure and our total liability for any part we warrant. RockJock’s liability under this warranty shall be limited to the cost for repair, replacement or an upgrade of the product (at RockJock’s sole and absolute discretion). Upgrade cost would be at the user’s expense. Consequential costs such as, but not limited to labor fees, loss of use, loss of revenue, loss of time, towing fees or freight charges are not covered. Any product that, in the opinion of RockJock, has been abused, altered, incorrectly installed or used in competition is not covered. Nothing in this warranty is intended to be a representation by RockJock that offroad component failures cannot occur.

Warranty Procedure:

Contact your RockJock dealer [RENO OFF-ROAD] or RockJock directly about the problem prior to removing any part from the vehicle. If it appears that the part is warrantable through means of verbal and/or written communication and photos, you will be given a Return Materials Authorization (RMA) Number and asked to return the part to RockJock, freight prepaid. If the part is found to be warrantable, it will be repaired or replaced and returned to you. All freight charges are the customer’s responsibility. If a replacement part is needed before the part in question can be returned, you must first purchase the replacement part. Then, if the part in question is deemed warrantable, you will be credited / refunded.
