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!

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

I needed some parts and had to replace 1 lower control arm and their customer service is great. Helped with answering my questions and got parts shipped quickly.

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!

Great company! I have used there products consistently with no complaints with quality you can see and feel. From my experience, their customer service is also amazing. Core 4x4 has no issues standing behind their already amazing products and will quickly and professionally solve issues may they arise. I will continue to be a customer.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

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

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
