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.

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.

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.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

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 have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!
