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.

Upgrade today and experience the difference in stability, comfort, and off-road performance!

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

Great product, excellent customer service. I mistakingly ordered a track bar for the wrong year model and Korby helped me out by sending me the correct part that I needed no questions asked. I highly recommend.

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!

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

Great Experience. I wanted to make changes to my order and Korby was more than willing to work with me to get everything corrected. Hope to deal with these guys again in the future.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!
