This 8-piece set provides unmatched strength, articulation, and adjustability, outperforming all other aftermarket options. Whether tackling rugged trails or cruising the highway, this upgrade enhances handling, axle alignment, and overall suspension geometry.

Key Features and Benefits

  • Heaviest tubing for upper and lower control arms – Lower control arms are constructed from 1.75” OD DOM tubing with a 5/16” wall thickness, while upper control arms use 1.5” OD DOM tubing with the same robust wall thickness for maximum durability.
  • Johnny Joints for superior flexibility – Each control arm is equipped with Johnny Joints at both ends for unmatched articulation and longevity. The front upper control arms feature a U-bracket at the axle end, attaching to the factory-installed bushing.
  • Adjustable for lift heights from 0 to 6 inches – Enables precise alignment correction, axle centering, and pinion angle optimization to eliminate driveline vibrations.
  • Recommended pairing – When all 8 control arms work in sync, your suspension is fully dialed in for improved handling and off-road capability.

Durable Powder Coating for Maximum Protection

Every control arm undergoes a two-stage powder coating process for superior durability and corrosion resistance. A zinc primer base coat enhances rust protection, while the top coat—available in 10 color options—provides long-lasting resilience and customization.

Proudly Made in the USA

The Crawl Series reflects the highest standards of American manufacturing. Built in Orem, UT, using locally sourced materials, every component undergoes rigorous quality control to ensure maximum strength, reliability, and longevity.

Optional Hardware Upgrade

This kit is designed for straightforward installation using factory hardware. For those dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available separately to ensure a seamless setup.

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

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.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.
