Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

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.

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

Great product for a good price. Customer service is top notch, I had an issue which was self cause and Core 4x4 helped me out even though it was my own fault. Would definitely recommend and use them again.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

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.

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

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.
