Whether you're looking to improve ride comfort, re-center your rear axle, or enhance off-road capability, this set provides a significant upgrade over factory components.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75” OD DOM tubing with a 5/16” wall thickness, these control arms provide unmatched strength and longevity.
  • Enhanced Flexibility and Strength – Features a Johnny Joint at the adjusting end for maximum articulation and a tapered polyurethane bushing at the axle end to absorb road vibrations and enhance durability.

  • Optimized Suspension Geometry – Improves handling and stability by correcting rear axle positioning and maintaining proper suspension angles.
  • Recommended Pairing – Pair with the Camp Series Rear Track Bar (CMP-J-JT-RTB1) for a fully optimized rear suspension system, ensuring maximum axle control and alignment stability.

Two-Stage Powder Coating for Maximum Protection

Each control arm undergoes a two-stage powder coating process for long-lasting durability and corrosion resistance. Zinc Primer Base Coat – Protects against rust and harsh conditions. Top Coat in 10 Custom Colors – Provides a tough, stylish finish and additional durability.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.
