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 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.

Great chair keeps you feeling cool!
I love the mesh areas - it keeps you feeling cool. I love the high back and neck area (it’s adjustable) the seat tilts back and allows you to relax (for me it’s a good back stretch ) I recommend this chair for any office use!

Sturdy and Comfortable
I’m really impressed with this ergonomic office chair. Assembly was incredibly easy I had it put together much faster than I expected, and everything fit together perfectly without any frustration. The teal green color is beautiful and one of my absolute favorites; it adds such a nice pop to my workspace. As a heavier person, I’m always cautious about weight capacity, but this chair feels genuinely solid and supportive. No wobbling, no sinking just sturdy, reliable construction. The seat cushion is comfortable for long hours at the computer, and the back support has made a noticeable difference in reducing my back pain. I also appreciate how easy it is to clean. A quick wipe keeps it looking fresh, and the material doesn’t trap dust or pet hair. The wheels glide smoothly, making it easy to roll and turn without any effort. For the price, the quality and value are fantastic. This chair has definitely made my workdays more comfortable. I highly recommend it especially for anyone who’s heavier and hesitant about sturdiness.

Great chair — comfortable, sturdy, and surprisingly easy to assemble
The first thing that impressed me was how steady and solid it feels. It’s not wobbly or flimsy at all, and the base and wheels roll smoothly without feeling cheap. Once assembled, it feels like a chair that will last. Assembly was also easier than expected. The instructions were straightforward, and all the parts lined up well. My 12-year-old son helped assemble it and was able to do most of it himself with some effort. Comfort-wise, it’s excellent for everyday use. The mesh back is breathable, the seat feels supportive, and the tilt adjustment (90–125°) is a nice bonus when I want to lean back and relax. The 3D armrests are also a great touch and help with positioning for desk work. Overall Nice chair

Sturdy, comfortable and solid chair for focused-workers
Color: Onyx Black
I LOVE THIS CHAIR! I've had a manager's style leather chair for the past four years from one of the office supplies big box stores and the armrests began to wear off, so the need for a suitable replacement was needed. Immediately, I knew how badly my posture was in the former chair and the ergonomics of this chair are 100% comfortable. The lumbar support is a little difficult to adjust correctly and that would be my only item for the makers to improve in future iterations. Overall, I am impressed with the quality, ease of assembly and downright comfort of this chair. I enjoy the settings especially the one to lock-in the recline degree of the back halfway and the leg rest is durable and strong. This change was for the better and I'm way more energized to get through my digital workflows for hours at a time without any fatigue. The item is cheaper than when I bought it and that's an absolute steal and bargain with much value hopefully for years to enjoy.
