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!

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.
