Maximize Caster Control and Front-End Stability

Upgrade your Jeep Wrangler JK (2007-2018) with the Cruise Series Front Control Arm Set, designed to restore proper caster angles, improve axle centering, and enhance overall drivability. Whether you're addressing factory alignment deficiencies or correcting geometry changes from a lift, this set provides the optimal balance of strength, adjustability, and control for both on-road stability and off-road articulation.

Key Features and Benefits

  • Regain Caster Improve Steering Control – Factory suspension geometry and small lifts reduce caster angle, leading to wandering steering and instability. This set corrects caster and re-centers the front axle, ensuring a more stable, controlled ride.
  • Heavy-Duty Steel Construction – Built to outlast and outperform factory control arms, these arms offer superior impact resistance and long-term durability.
  • Tapered Polyurethane Bushings for Responsiveness – Designed for improved articulation, vibration dampening, and better road feel, compared to standard rubber bushings.
  • Full Adjustability for Lifted Vehicles – Ideal for suspension lifts from 0 to 6 inches, restoring proper axle position and caster alignment to maintain smooth handling and reduced driveline vibrations. For lifts beyond 6 inches, contact us for additional solutions.
  • Complete Suspension Solution – For full control over axle positioning, pinion angles, and suspension geometry, pair this set with our Cruise Series Rear Control Arm Set (CRS-J-JK-RS4). Together, they provide a comprehensive upgrade for improved handling, stability, and long-term durability.

Two-Stage Powder Coating for Maximum Protection

Every Cruise Series Front Control Arm undergoes a two-stage powder coating process for maximum durability and corrosion resistance: Zinc primer base coat prevents rust and enhances longevity. Durable top coat available in 10 custom colors for added style and resilience.

Effortless Installation

The Cruise Series Front Control Arm Set is designed for quick and easy installation using factory hardware. For vehicles with rusted or seized bolts, we offer optional Grade 8 hardware kits separately to simplify the installation process.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series Front Control Arm Set reflects the highest standards of American craftsmanship. By choosing CORE 4X4, you're investing in high-quality, American-made products built for the toughest driving conditions.

For a complete suspension solution, pair this with the Cruise Series Rear Control Arm Set (CRS-J-JK-RS4) to fully adjust and optimize axle positioning, pinion angles, and handling characteristics.

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!!!!

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!
