Premium shock packages from Rancho and King are offered here as options so that you can select the shock brand and performance level that matches your driving style. We always recommend adjustable shocks, as they allow the ride to be tuned to match the terrain and driver’s preference.

- RockJock Spec. Dual-Rate Springs - Feature a soft initial rate that absorbs small bumps and trail chop, to deliver a smooth, comfortable ride, while a firmer secondary rate helps soak up larger impacts and reduce bottoming. A key differentiator of RockJock spec. dual-rate springs are the positioning of the crossover point between the initial and secondary spring rates so that a portion of the softer initial rate is available and active at ride height before crossing over to the firmer secondary rate deeper into the travel.
- Bump Stop Spacers - Proper bump stop extensions are a must and our heavy-duty kits stand up to hard use while keeping the tires off of your LJ’s fenders!
- Johnny Joint Control Arms – Heavy-duty adjustable upper control arms feature RockJock Johnny Joints, 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 are so trusted, that they are used by multiple commercial suspension companies, for both street and off-road suspension systems.
- Johnny Joint Trac Bars - Heavy-duty trac bars included are our adjustable length chromoly front and rear units. Our trac bars combine a precise fit with increased strength and adjustable length to perfectly center front and rear axles under the vehicle. High-articulation Johnny Joint ends provide maximum durability and suspension flex.
- Antirock Sway Bars - Antirocks allow for maximum suspension articulation while providing maximum 4-wheel traction.
- Currectlync Steering System - For maximum strength, reliability, and confidence off-road, upgrade your steering!
- Axle Housing Johnny Joints - Adding this simple kit to your Pro Edition Suspension System converts 2 more pivoting points in your suspension to high-articulation Johnny Joint rod ends.
- Shock Packages - Select from a range of performance shocks with race-proven technology from Rancho and King to meet your requirements.
- Rear Shock Relocation Brackets - Recommended for use when using this suspension kit in conjunction with a factory differential to push the lower shock mounting location back outward to an accessible location.
- Actual lift height may vary due to factory build specs. and added equipment and accessories.
- 33 in. tires – no other vehicle modification necessary
- 35 in. tires – 1 in. Body Lift and a 1 in. Motor Mount Lift or aftermarket fenders, high-clearance fenders required
- Larger Than 35 in. Tires – we have found provide diminishing return without dramatic modifications to the vehicle
- 4.5 in. wheel backspace is recommended for all tire sizes
- This amount of lift on an LJ makes a transfer case tail shaft slip yoke eliminator kit not necessarily mandatory, but it’s highly recommended. The kit we recommend is from Tom Wood’s Driveline.

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.
