Key Features and Benefits

  • Complete suspension overhaul – This set replaces all eight factory control arms, optimizing suspension geometry, axle alignment, and handling for both lifted and stock-height vehicles.
  • Heavy-duty steel tubing construction – Built from rugged steel tubing, these control arms provide maximum strength and impact resistance, outperforming factory components.
  • Tapered polyurethane bushings – Equipped with polyurethane bushings at both ends, these arms offer improved responsiveness, vibration dampening, and durability over traditional rubber bushings.
  • Fully adjustable for lifted vehicles – Designed to accommodate 0 to 6 inches of lift, allowing for precise axle centering, pinion angle adjustments, and improved ride quality. For lifts beyond 6 inches, contact us for additional options.

Regain Caster and Alignment for Maximum Drivability

Adjusting your control arms allows for proper suspension geometry, helping to correct driveline vibrations in the rear and reducing wandering or rut tracking in the front, significantly improving handling and comfort.

Complete Suspension Solution

For full control over axle positioning, geometry, and overall drivability, pair this kit with our Cruise Series Front Track Bar (CRS-J-JK-FTB1) and Rear Track Bar (CRS-J-JK-RTB1) to achieve maximum stability and precision on and off the road.

Two-Stage Powder Coating for Maximum Protection

Each component in this kit undergoes a two-stage powder coating process for long-lasting durability and corrosion resistance. The zinc primer base coat prevents rust and protects against environmental damage, while the durable top coat, available in 10 custom colors, provides added protection and personalization. Custom colors are available upon request.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series Complete Control Arms Set is built to the highest standards of American craftsmanship. By choosing CORE 4X4, you’re investing in high-quality, American-made products designed to withstand the most demanding conditions.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

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.

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

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.
