Optimized Rear Suspension for Maximum Performance and Comfort

Take your Toyota 4Runner (2003-Present) to the next level with the Cruise Series Complete Rear Kit—designed to enhance stability, improve handling, and optimize suspension performance both on and off the road. This comprehensive upgrade includes Rear Upper and Lower Control Arms and a Rear Track Bar, engineered for unmatched strength, durability, and adjustability.

What’s Included in the Kit?

  • Cruise Series Rear Upper Control Arms (CRS-T-4R-03-RU2)
  • Cruise Series Rear Lower Control Arms (CRS-T-4R-03-RL2)
  • Cruise Series Rear Track Bar (CRS-T-4R-03-RTB)

Key Features and Benefits

  • Improved Rear Axle Centering Stability – Keeps the axle properly aligned, reducing lateral movement for better control on and off the road.
  • Precise Adjustability – Designed to accommodate lifts from 0 to 6 inches, allowing for exact pinion angle adjustments and proper alignment.
  • Heavy-Duty Construction for Maximum Strength – Made from robust steel tubing, ensuring long-lasting durability and improved resistance to off-road impacts.
  • Tapered Polyurethane Bushings for Reduced NVH – Minimizes noise, vibration, and harshness, improving both ride quality and suspension longevity.
  • Enhanced Handling Tire Wear Reduction – By keeping the rear axle properly positioned, this kit reduces suspension wear and extends tire life.

Built for Lifted and Stock Vehicles

If you’ve lifted your Toyota 4Runner, improper axle positioning can cause handling issues, uneven tire wear, and drivetrain stress. This kit allows for precise axle centering, pinion angle correction, and optimized suspension geometry, ensuring smooth handling and improved drivability at any lift height.

Dual-Stage Powder Coating for Superior Durability

Each component in the Cruise Series Rear Kit undergoes a two-stage powder coating process for enhanced rust protection and corrosion resistance. The zinc primer base coat forms a barrier against the elements, while the top coat—available in 10 color options—adds a personalized, durable finish.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series Rear Kit is built in-house using high-quality domestic materials. Our commitment to American manufacturing ensures the highest level of craftsmanship, strength, and reliability.

Optional Hardware Upgrade

This kit is designed for easy installation using factory hardware. If your existing bolts are rusted or worn, we offer optional Grade 8 hardware kits, available separately, to ensure a hassle-free installation.

In Conclusion

The Cruise Series Complete Rear Kit is the ultimate upgrade for Toyota 4Runner owners looking to improve handling, eliminate axle shift, and enhance off-road capability. Whether you're lifting your vehicle or just want a more durable suspension system, this kit ensures proper alignment, smoother handling, and increased suspension longevity. Upgrade today and experience the confidence of a reinforced suspension built to handle any terrain.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly 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.

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
