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!

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

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.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

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.
