Product Details

2009–Present Ram 1500 Race Series Rear Upper Control Arms SKU: RC-R-15-2009-RU2

Maximize your Ram 1500’s rear-end performance with the Race Series Rear Upper Control Arms. Engineered for aggressive handling and precise axle control, these control arms provide exceptional strength, adjustability, and durability. 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.
  • Rock Jock 4x4 Johnny Joints – Provides industry-leading articulation, adjustability, and long-lasting performance under extreme conditions.

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.

Made in the USA

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.

Optional Hardware Upgrade

For a seamless installation, upgrade to our Grade 8 hardware kit, perfect for replacing stubborn or rusted factory bolts.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

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!
