Superior Comfort and Flexibility

Upgrade your Toyota 4Runner's suspension system with the Camp Series Rear Upper Control Arms, engineered for model years 2003-2024. These control arms offer improved on-road comfort and off-road performance, delivering superior durability and flexibility over factory components.

Key Features and Benefits

  • Robust Construction for Strength and Performance – Built from DOM Tubing with a 5/16” wall thickness, the Camp Series Rear Upper Control Arms are designed to excel under demanding conditions.
  • Johnny Joint Tapered Polyurethane Bushing – A Johnny Joint at the adjusting end ensures superior articulation and flexibility, while our unique tapered polyurethane bushing at the axle end dampens vibrations for smoother performance.
  • Critical Adjustability for Precise Alignment – Fully adjustable to accommodate lifts from 0 to 6 inches, allowing for accurate alignment correction and rear axle re-centering.
  • Optimized Pinion Angle – Proper pinion angle adjustments help avoid driveline vibrations, making these control arms essential for lifted vehicles.
  • Complete Rear Suspension Solution – Pair them with our Rear Lower Control Arms for a fully optimized rear-end solution, maximizing control and stability.

Two-Stage Powder Coating for Durability

Every control arm undergoes a rigorous two-stage powder coating process: Zinc primer base coat ensures exceptional corrosion resistance. Durable top coat, available in 10 color options, provides long-lasting protection while giving your 4Runner a customized appearance.

Proudly Made in the USA

Crafted at our Orem, UT facility, the Camp Series Rear Upper Control Arms reflect the highest standards of American manufacturing.

By sourcing materials locally and overseeing every step of production, we ensure exceptional quality and reliability.

Optional Hardware Upgrade

Installation is straightforward with factory hardware, and we also offer optional Grade 8 hardware kits for replacing rusted or stubborn bolts, ensuring a hassle-free setup.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

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.

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.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

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!
