Optimize Suspension Performance for Maximum Control

Upgrade your Jeep Wrangler JK’s rear suspension with the Cruise Series Rear Lower Control Arms. Designed to outperform factory components, these arms deliver improved handling, better axle control, and increased off-road durability. Whether you're hitting the trails or cruising the highway, these control arms provide a smoother ride and enhanced stability while correcting suspension geometry.

Key Features and Benefits

  • Heavy-Duty Steel Tubing Construction – Built for maximum strength and longevity, ensuring superior performance over factory control arms.
  • Tapered Polyurethane Bushings – Absorb vibrations and provide better responsiveness than traditional rubber bushings.
  • Full Rear-End Suspension Solution – When paired with our Cruise Series Rear Upper Control Arms (CRS-J-JK-RU2), these lower control arms provide complete alignment correction, axle centering, and optimal suspension performance.
  • Corrects Pinion Angle – Adjustability allows for proper pinion angle correction when paired with our Upper Rear Control Arms, eliminating driveline vibrations for a smoother ride.
  • Improves Suspension Geometry – Helps re-center the rear axle and reduces tire wear and stress on suspension components.

Precise Adjustability for Lifts

The Cruise Series Rear Lower Control Arms are fully adjustable to accommodate lifts from 0 to 6 inches, allowing for:

  • Pinion angle correction when paired with our Upper Rear Control Arms.
  • Re-centered rear axle for better stability and handling.
  • Reduced stress on tires and suspension components, prolonging their lifespan.

For lifts beyond 6 inches, contact us for custom solutions.

Durable Two-Stage Powder Coating

Our control arms undergo a two-stage powder coating process for maximum corrosion resistance and long-lasting durability: Zinc primer base coat – Protects against rust and environmental wear. Durable top coat – Available in 10 color options to personalize your Jeep’s look.

Proudly Made in the USA

Manufactured in Orem, UT, our Cruise Series Rear Lower Control Arms are built to the highest American manufacturing standards, ensuring quality, reliability, and strength.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

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 ! ! !

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

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!
