RockJock 4x4 Front Axle Housing Johnny Joint Kit Jeep Wrangler | Gladiator 2018-2023
$226.00
RockJock’s Johnny Joint Front Axle Housing Kit replaces the front differential housing upper control arm bushings on your Jeep JL Wrangler or JT Gladiator with Johnny Joint rod ends from RockJock, allowing you to get maximum articulation out of your front suspension!

This kit includes Johnny Joint inserts that replace the rubber bushings on the axle housing, greaseable bolts, and an installation tool.

RockJock’s Johnny Joints are the original and most durable high-articulation urethane suspension joint on the market. Johnny Joints feature a smooth steel ball that pivots inside a proprietary urethane shell to provide over 30 degrees (per joint) of quiet, shock-dampening articulation - without the excessive deflection found in soft rubber-based flex joints. Johnny Joints deliver a smooth, comfortable on-road ride with the ultimate in-off-road capability. They are so trusted, that they are used by multiple commercial suspension companies, for both street and off-road suspension systems.

Joints are fully greaseable and are finished in clear zinc plating

Warranty:

John Currie Performance Group, Inc. DBA Rock Jock (“RockJock”) warranties, to the original purchaser with physical proof of purchase, all items manufactured by RockJock to be free from defects in materials and workmanship for the limited period of two (2) years from the stated delivery date on invoice. Any alteration or improper use as determined by RockJock in its sole discretion will void this warranty. Further, we disclaim any liability for action resulting from failure or parts durability. 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.

This warranty is not assignable and non-transferable. 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 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.
