RockJock's Pro Edition Johnny Joint Suspension System for 4XE Hybrid JL Wranglers and Unlimiteds provides 3.5 inches of lift and allows for efficient clearance of up to 37 in. tall tires (larger tires will require aftermarket fenders and minor trimming)!

This kit is comprised of only the highest end components in the areas of strength, fit, finish, function, and the engineering to back them, delivering a smooth, comfortable on-road ride with the ultimate in off-road capability - all in a complete, direct bolt-on kit.

This kit is designed specifically for the serious off-roader who not only wants to lift their vehicle and install big tires, but also wants to tackle the toughest trails in the country with confidence and ease.

Premium shock packages from Bilstein, 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 Fits:

  • JL Wrangler Unlimited (4-door) - All 4XE Hybrid Models
  • JL Wrangler (2-door) - All 4XE Hybrid Models

Kit Includes:

  • 3.5 in. Lift Dual-Rate Front And Rear Springs
  • Front Coil Spring Shim
  • 8 Johnny Joint Adjustable Control Arms
  • Johnny Joint Adjustable Front Trac Bar (forged, organically shaped)
  • Johnny Joint Adjustable Rear Trac Bar
  • Rear Trac Bar Geometry Correction Bracket
  • Front and Rear Bump Stop Kits
  • Front and Rear Adjustable Sway Bar Links w/ Sealed Ends
  • Front Brake Line Relocation Brackets
  • All Required Hardware

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 JL 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 Bars - Heavy duty adjustable length Trac Bars included are our forged chromoly, organically shaped front bar and our chromoly rear bar. 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.

Optional Add-On Components - Add-on components enable the RockJock Pro 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 Pro Edition Suspension System converts 2 more pivoting points in your suspension to high articulation Johnny Joint rod ends.

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.

Smell
Size: Queen (2 Count), Color: Original White (Cooling)
The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back. Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.
