Total Suspension and Steering Control for Maximum Performance

Upgrade your Jeep Wrangler JK (2007-2018) with the Camp Series Complete Kit With Steering, the most comprehensive suspension and steering package designed to improve handling, durability, and off-road capability. This all-in-one kit delivers unmatched strength, precision alignment, and superior steering response, making it the ultimate choice for Jeep enthusiasts who demand the best.

Key Features and Benefits

  • Complete suspension and steering overhaul – Replaces all eight control arms, front and rear track bars, and the steering system for unmatched control and handling.
  • Premium DOM tubing construction – Built from 1.75” OD DOM tubing for lower arms and 1.5” OD DOM tubing for upper arms, all featuring a 5/16” wall thickness for extreme durability.
  • Improved steering response and control – The 2.5-ton aluminum steering kit enhances precision, eliminates play in the linkage, and keeps your Jeep responsive on and off the road.
  • Optimized caster and axle alignment – Adjustable control arms correct caster angles to prevent wandering, while adjustable front and rear track bars re-center axles after lifting.

Johnny Joint Technology for Maximum Flexibility

Features RockJock Johnny Joints at the adjusting ends for extreme articulation, while tapered polyurethane bushings at the axle ends reduce vibrations and extend component longevity.

Recommended Pairing

For even greater performance and body roll reduction, pair this kit with our Camp Series Sway Bar End Links (CMP-J-JK-ELS4).

Enhanced Handling, Stability, and Steering Performance

Lifting your Jeep without correcting caster angles and axle alignment can result in steering instability, poor handling, and uneven tire wear. This fully adjustable kit corrects suspension geometry, ensuring your Jeep drives straight and stable while maintaining maximum articulation and off-road capability. The 2.5-ton aluminum steering kit provides a stronger, more responsive connection between your steering wheel and the road.

Designed for straightforward installation using factory hardware, with optional Grade 8 hardware kits available separately for rusted or worn-out bolts.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.
