Key Features and Benefits

  • Heavy-Duty Construction – Built from 1.75" OD DOM tubing with .313" wall thickness on the lower control arms and 1.5" OD DOM tubing with .313" wall thickness on the upper control arms, providing superior strength over factory components.
  • Optimized Suspension Geometry – Fully adjustable control arms allow for precise axle positioning, pinion angle adjustments, and suspension correction, accommodating lifts from 0 to 6 inches.
  • Premium Joint Technology – Features Johnny Joints at the adjusting ends for superior articulation and tapered polyurethane bushings at the axle ends for vibration dampening and extended longevity.
  • Recommended Pairing – For a complete rear suspension solution, pair this kit with our Camp Series Rear Track Bar (CMP-J-JL-RTB1) to further improve stability and axle alignment.

This fully adjustable rear control arm set is designed to restore proper suspension geometry, correct alignment after lifting, and maximize handling for both on-road driving and off-road adventures. Whether you're tackling rough terrain or cruising on the highway, these control arms enhance ride quality, prevent premature tire wear, and improve suspension articulation.

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

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!
