Unmatched Strength, Adjustability, and Off-Road Performance

Upgrade your Jeep Cherokee XJ (1984-2001) and Jeep Comanche MJ (1986-1992) with the Crawl Series Complete Front Control Arms Set, designed to provide superior off-road resilience, precise alignment control, and improved on-road handling. This set replaces factory components with high-strength materials and fully adjustable features, making it the ideal solution for lifted vehicles seeking enhanced suspension geometry, stability, and flexibility.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 5/16” wall thickness DOM tubing, these control arms provide exceptional durability and strength for extreme off-road conditions.
  • Johnny Joints for Maximum Flexibility – Lower control arms feature Johnny Joints at both ends, while upper control arms utilize a Johnny Joint at the adjusting end, providing superior articulation and smoother suspension movement.
  • Full Adjustability for Lifted Vehicles – Accommodates 0 to 6 inches of lift, allowing for precise caster and pinion angle correction, ensuring optimal handling and improved stability at any ride height.
  • Enhanced Suspension Geometry – Helps correct axle alignment, optimize steering response, and reduce suspension stress, making it a must-have upgrade for lifted Jeeps.
  • Recommended Pairing – For a complete front-end suspension upgrade, pair with the Crawl Series Front Track Bar (CRL-J-XJMJ-FTB1) to ensure precise axle centering and maximum stability.

Two-Stage Powder Coating for Maximum Protection

Each control arm undergoes a two-stage powder coating process for superior corrosion resistance and durability. The zinc primer base coat protects against rust, while the top coat—available in 10 custom colors—lets you personalize your suspension setup.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

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👌🏽

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.
