RockJock 4x4 JL/JT & JK Adjustable Front Upper Bump Stops Jeep Wrangler | Gladiator 2007-2023

Free Shipping
RockJock® Adjustable Front Bump Stops for JL/JT front as well as JK front are a completely different take on the concept of bump stops! So unique in fact that they were awarded SEMA's 2023 Best New Off-Road/4-Wheel Drive Product of the year! In high articulation situations, an axle housing mounted bump stop ends up rotating inward toward the center of the vehicle, often missing the upper bump stop entirely (see diagram in the photo gallery). By lowering the front bump stop, and being able to adjust it's length, you are able to guarantee bump stop contact when and where you need it. Our adjustable kit features billet aluminum components and 5/16" thick steel shims that are able to be added and subtracted for fine tuning, while the bump stop assemblies are on the vehicle. You simply put a socket on the upper bolt to hold it in place, loosen the bump stop body with the supplied spanner wrench, add or subtract bump stop shims as needed and then tighten the assembly back up! The vehicle's factory yellow bump stop cushions are retained and relocated by inserting them back into the bottom of the new aluminum RockJock bump stop bodies. This provides factory "feel" when the bump stops make contact. Finish is clear anodize on the aluminum and zinc plating on the spacers and bolts.

Kit Includes:
  • (2) Bump Stop Spacer (upper half)
  • (2) Bump Stop Spacer (lower half)
  • (8) 5/16" Bump Stop Spacer Shim
  • (2) M12-1.75 x 50mm Long Flanged Hex Bolt
  • (1) Spanner Wrench
Fitment Specs.:
  • See diagram in the photo gallery for minimum & maximum adjusted heights
  • Fits the upper bump stop cup on all factory JL, JT & JK frames
  • Intended for use with 2 1/2" of lift and greater
  • If this kit is used with other than a stock axle, the height of the bump stop pad on the aftermarket axle must be taken into account. If it's height differs from the height of a factory bump stop pad, you must adjust this bump stop kit to accommodate the difference
  • NOT for use with JT Mojave model
  • JL Extreme Recon package includes factory spacers. This kit should not be stacked or used "in addition to" the stock spacers
  • JL 392 model feature a different bump stop height than other JLs, thus this kit will require less shim than it would on a similarly equipped non-392 model
  • Required spacer amounts on a JK/JKU with similar lift height, shocks, and tire/flare combinations may not be the same as a JL/JLU/JT
Fitment:
  • Jeep Wrangler JL 2018-2023
  • Jeep Wrangler JK 2007-2017
  • Jeep Gladiator JT 2020-2023

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 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.
