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 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.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

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

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.

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!
