Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

Ultimate Off-Road Performance

Upgrade your Jeep Wrangler JK with the Crawl Series Complete Set of Control Arms, the ultimate solution for superior off-road flexibility and on-road comfort. Engineered for strength, durability, and precision, this comprehensive kit surpasses all other aftermarket options, delivering unmatched performance and reliability for your off-road adventures.

What’s Included in the Kit?

  • Crawl Series front upper control arms – CRL-J-JK-FU2
  • Crawl Series front lower control arms – CRL-J-JK-FL2
  • Crawl Series rear upper control arms – CRL-J-JK-RU2
  • Crawl Series rear lower control arms – CRL-J-JK-RL2

Key Features and Benefits

  • Engineered construction – Lower control arms are made with 1.75” OD DOM tubing and 5/16” wall thickness for maximum durability, while upper control arms are constructed with 1.5” OD DOM tubing and 5/16” wall thickness for optimal strength.
  • Johnny Joints for extreme flexibility – Equipped with Johnny Joints at both ends, these control arms provide exceptional articulation and longevity. The front upper control arms feature a U-bracket at the axle end, seamlessly integrating with the factory-installed bushing.
  • Enhanced adjustability – Designed for effortless adjustability, accommodating lifts from 0 to 6 inches, allowing for precise alignment correction, front and rear axle re-centering, and pinion angle optimization to reduce driveline vibrations.
  • Recommended pairing – When used as a complete set, the synchronization of all 8 control arms maximizes performance and ensures your suspension is dialed in for any terrain.

Two-Stage Powder Coating for Durability

Each control arm undergoes a meticulous two-stage powder coating process. A zinc primer base provides superior corrosion resistance, while the durable top coat, available in 10 custom color options, adds extra protection and style. This process ensures long-lasting durability, even in the most demanding environments.

Proudly Made in the USA

The Crawl Series reflects the highest standards of American manufacturing. Produced in our Orem, UT facility, every component undergoes rigorous quality control, from sourcing local materials to final assembly.

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4
