Transform your Jeep Wrangler TJ/LJ with the Crawl Series Complete Set of Control Arms, a game-changing upgrade designed for off-road enthusiasts and on-road drivers alike. Built for exceptional durability, flexibility, and performance, this kit enhances handling, provides unmatched strength, and maximizes articulation to tackle even the most challenging terrains.

Key Features and Benefits

  • Superior articulation for off-roading – Equipped with Johnny Joints at both ends, allowing for unrestricted flex and maximum suspension movement without binding, ensuring top performance in extreme conditions.
  • Engineered for strength and durability – Lower control arms feature 1.75” OD DOM tubing, and upper control arms use 1.5” OD DOM tubing, both with a .313″ wall thickness, exceeding industry standards.
  • Optional double adjustability – Upgrade to double adjustability with left- and right-hand threaded joints on all arms for on-vehicle fine-tuning of axle centering, caster, and pinion angles.
  • Complete suspension solution – Pair this control arm set with Crawl Series front and rear track bars for total axle stability, improved handling, and superior suspension alignment.

Enhanced Adjustability for Peak Performance

The Crawl Series Complete Set of Control Arms accommodates lifts from 0 to 6 inches, allowing full adjustability to fine-tune your suspension geometry. Whether re-centering axles or dialing in caster and pinion angles, this kit ensures optimal performance on any terrain. For lifts beyond 6 inches, contact us for custom solutions.

Two-Stage Powder Coating for Maximum Protection

All control arms undergo a two-stage powder coating process for superior durability and corrosion resistance. A zinc primer base coat provides excellent rust protection, while the durable top coat—available in 10 color options—adds long-lasting protection and a custom aesthetic.

Proudly Made in the USA

Manufactured in Orem, UT, the Crawl Series reflects the highest standards of American craftsmanship. By choosing Crawl Series products, you’re investing in superior engineering while supporting local industries and rigorous quality control.

Simple Installation

This kit installs using factory hardware. If dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available separately for a hassle-free setup. For those selecting double adjustability, on-vehicle adjustments make fine-tuning effortless.

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

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
