Whether you're hitting the track, tearing up trails, or navigating everyday roads, this upgrade ensures superior stability and responsiveness.

Key Features Benefits

  • Precision Rear Axle Alignment – Eliminates pinion misalignment, reducing drivetrain stress and improving handling.
  • Lightweight 7075 Aluminum Construction – Crafted from aircraft-grade aluminum for extreme strength while reducing unsprung weight.
  • Fully Adjustable for Lifted Lowered Setups – Left- and right-hand threads allow in-place adjustments, accommodating lifts or drops up to 8 inches.

Recommended Pairing

For complete rear-end control, pair with the Race Series Rear Lower Control Arms (RC-R-15-2009-RL2).

Take Control of Your Rear Suspension

Lifting or lowering your Ram 1500 can throw off axle alignment and pinion angles, causing unnecessary strain on your suspension and drivetrain. The Race Series Rear Upper Control Arms solve this issue by providing full adjustability, allowing for precise axle positioning and improved ride quality. These control arms are a game-changer for anyone modifying their suspension.

Two-Stage Powder Coating

Choose our two-stage powder coating for exceptional corrosion resistance, starting with a zinc primer base followed by a durable topcoat in your preferred color. For those who prefer the raw, high-performance look, opt for the uncoated aluminum finish to showcase the strength of 7075 aluminum.

Proudly designed and manufactured in Orem, UT, these control arms are built to exceed industry standards. Every component is tested to ensure precision, durability, and American-made quality.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store
