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 products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!
