Complete Control Over Your Rear Suspension

Unleash the full potential of your Ram 1500 (2009–Present) with the Track Series Adjustable Rear Control Arm Set, designed to provide precision axle alignment, improved traction, and unmatched stability. Whether you're launching at the track, towing heavy loads, or tackling off-road terrain, these adjustable upper and lower control arms ensure your rear axle remains planted, eliminating wheel hop and maximizing power transfer.

What’s Included in the Set?

  • Track Series Adjustable Rear Upper Control Arms – TRK-R-15-2009-RU2
  • Track Series Adjustable Rear Lower Control Arms – TRK-R-15-2009-RL2

Key Features Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75" OD .313" wall DOM tubing, ensuring exceptional strength and durability to withstand extreme loads and terrain.
  • Rock Jock Johnny Joints at Both Ends – Fully serviceable and rebuildable, these joints allow for maximum articulation, eliminating suspension bind and improving ride quality.
  • Left- Right-Hand Threaded Adjustability – Allows for on-vehicle tuning of pinion angle, axle positioning, and suspension geometry without removal, making alignment quick and hassle-free.
  • Eliminates Wheel Hop Maximizes Traction – Factory rubber bushings cause axle deflection and oscillation under load, leading to wheel hop. These solid joints prevent unwanted axle movement, ensuring consistent tire contact and improved acceleration stability.

Recommended Pairing for Complete Control

For total control over your rear suspension, we recommend pairing this set with the Track Series Adjustable Rear Panhard Track Bar (TRK-R-15-2009-RPTB1). This ensures perfect axle centering, improved handling, and enhanced stability, eliminating any unwanted lateral movement in the rear suspension.

Maximize Rear Axle Stability Suspension Adjustability

When modifying your truck’s ride height, the factory control arms lack the adjustability needed to maintain proper pinion angle and axle alignment, leading to vibrations, poor handling, and reduced traction. The Track Series Adjustable Rear Control Arm Set allows you to fine-tune your suspension geometry, ensuring precise axle positioning and optimal power transfer.

Highly Durable Two-Stage Powder Coating

Every Track Series component undergoes a two-stage powder coating process for superior durability and corrosion resistance. A zinc primer base coat provides maximum rust protection, while the durable topcoat is available in 10 color options for a customized look.

Proudly Made in the USA

Every CORE 4X4 product is designed, manufactured, and tested in Orem, UT, ensuring superior craftsmanship and strict quality control. By keeping production local, we maintain high-quality material selection, precision machining, and consistent durability.

Final Thoughts

The Track Series Adjustable Rear Control Arm Set is an essential upgrade for Ram 1500 owners looking to eliminate wheel hop, dial in suspension geometry, and improve overall handling. For total rear axle control, pair this set with our Track Series Adjustable Rear Panhard Track Bar (TRK-R-15-2009-RPTB1) to achieve perfect suspension balance and stability.

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.

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.

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!
