RockJock's Sport Edition Johnny Joint Suspension System for JT Gladiators with the 3.6L V6 or 2.0T gas engine provides 3 1/2 inches of lift and allows for efficient clearance of up to 37 in. tall tires (larger tires will require aftermarket fenders and minor trimming)!
Comprised of only the highest end components in the areas of strength, fit, finish, function, and the engineering to back them, this kit is more than sufficient for those who want to lift their vehicle, install big tires and hit some intermediate trails on the weekend!
For those who intend to do more serious 4 wheeling and rock crawling, you'll want to look at all of the upgrade parts that RockJock has to offer that can be added to this kit to get your vehicle to it's full potential at any level of off-roading!
Premium shock packages from Fox 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.

Kit Features:
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 is 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 the shiny new JT 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. Learn more here.
Johnny Joint Trac Bar - Forged chromoly, organically shaped front trac bar combines a precise fit with incredible strength and rigidity that is only available via forging. The adjustability feature allows you to perfectly center front and rear axles under the vehicle. High-articulation Johnny Joint ends provide maximum durability and suspension flex.
 
Optional Add-On Components - Add-on components enable the RockJock Sport Edition Suspension Lift to be customized for increased off-road capabilities and tuning.
Shock Packages - Select from a range of performance shocks with race-proven technology from Bilstein, Fox and King to meet your requirements.
Antirock Sway Bars - The most popular off-road sway bar on the market enhances off-road driving capabilities with balanced performance of front and rear suspension in rugged off-road conditions. Off-road traction is improved with increased suspension flex and by equalizing and distributing the weight of the vehicle over all four tires - without the overly loose feeling created by sway bar disconnects.
Currectlync Steering System - For maximum strength, reliability and confidence off-road, upgrade your steering!
Geometry Correction Brackets - Depending on your usage and application, check out our Geometry Correction Bracket sets and see if they are for you.
Axle Housing Johnny Joints - Adding this simple kit to your Sport Edition Suspension System converts 2 more pivoting points in your suspension to high articulation Johnny Joint rod ends.
