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.

What’s Included in the Kit?

Cruise Series Front Upper Control Arms (CRS-J-JK-FU2)
Cruise Series Front Lower Control Arms (CRS-J-JK-FL2)

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.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

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.

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.

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.
