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.

Effortless Installation

Designed for easy bolt-on installation, these control arms use factory hardware. If dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately for a hassle-free setup.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

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!
