Maximize Alignment and Suspension Performance

Upgrade your Jeep Wrangler JK (2007-2018) with the Cruise Series Front Upper Control Arms, engineered for increased strength, durability, and precise alignment control. Whether you’re tackling rugged trails or daily driving, these control arms provide the stability and adjustability needed to maintain proper suspension geometry and improve overall handling.

Key Features and Benefits

  • Strength durability – Constructed from robust steel tubing, providing superior resilience over factory parts.
  • Precise adjustability – Accommodates 0 to 6 inches of lift, helping restore alignment and drivability after suspension modifications.
  • Unique U-bracket design – The axle end features a U-bracket, allowing easy installation onto the factory-mounted axle bushing.
  • Tapered polyurethane bushings – At the adjusting end, these bushings provide enhanced stability, improved responsiveness, and reduced vibrations.
  • Complete suspension solution – Pair with Cruise Series Front Lower Control Arms (CRS-J-JK-FL2) to fully recenter the front axle and correct caster for maximum handling performance.

Optimized for Alignment and Caster Correction

Lifting your Jeep changes its suspension geometry, which can lead to misalignment, poor handling, and increased suspension wear. Our adjustable Front Upper Control Arms allow you to:

  • Fine-tune caster angle for improved steering feel and high-speed stability.
  • Correct pinion angle to reduce driveline vibrations, especially after installing a lift.
  • Re-center the axle when paired with our Cruise Series Front Lower Control Arms (CRS-J-JK-FL2), ensuring proper suspension geometry and enhanced drivability.

For lifts above 3 inches, pairing Front Uppers with Front Lowers is highly recommended to achieve full caster control and optimal axle positioning.

Two-Stage Powder Coating for Maximum Protection

Each Cruise Series Front Upper Control Arm undergoes a two-stage powder coating process to ensure maximum corrosion resistance and long-lasting durability. Zinc primer base coat prevents rust and protects against harsh conditions. Durable top coat available in 10 custom colors for added protection and customization.

Effortless Installation

Our Cruise Series Front Upper Control Arms are designed for quick and straightforward installation using factory hardware. If replacement bolts are needed, we offer optional Grade 8 hardware kits separately for a hassle-free setup.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series Front Upper Control Arms reflect the highest standards of American craftsmanship. By choosing CORE 4X4, you're investing in high-quality, American-made suspension components built for durability and superior performance.

For a complete suspension solution, pair these with Cruise Series Front Lower Control Arms (CRS-J-JK-FL2) to fully optimize your Jeep’s handling, stability, and off-road performance.

Upgrade today and experience improved alignment, superior durability, and American-made quality with CORE 4X4’s Cruise Series control arms!

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

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!!!!

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.
