The Ultimate Suspension Upgrade

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.

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. 👍👍

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.
