Unmatched Strength, Control, and Off-Road Performance

Upgrade your Ford Bronco (2021-Present) with the Camp Series Complete Rear Kit, designed to provide exceptional durability, improved handling, and superior off-road flexibility. Whether you're hitting the trails or cruising the highway, this kit offers the perfect balance of strength and comfort, making it an essential upgrade for any Bronco owner.

Key Features Benefits

  • Heavy-duty DOM tubing construction – Built from 5/16” wall thickness DOM tubing, this kit offers superior strength and resilience, ensuring long-term durability in even the harshest off-road conditions.
  • Hybrid bushing joint design – Featuring tapered polyurethane bushings at the fixed ends for reduced road vibrations and improved comfort, combined with RockJock Johnny Joints at the adjusting ends for exceptional articulation and off-road performance.
  • Full adjustability for pinion axle alignment – Designed to accommodate lifts from 0 to 6 inches, allowing for precise pinion angle correction, axle recentering, and improved handling, reducing stress on tires and suspension components.
  • Optimized for on-road off-road performance – Whether tackling rocky terrain or daily commutes, this kit enhances overall ride quality, eliminates excessive tire wear, and provides better control on uneven terrain.

Superior Adjustability Performance

Lifting your Ford Bronco can disrupt suspension geometry, leading to axle misalignment, poor handling, and increased wear on suspension components. This kit ensures correct rear axle positioning, improving handling and vehicle control. Fine-tuned suspension adjustments allow for pinion angle correction, reducing driveline vibrations and improving power transfer. Whether at stock height or running a 6-inch lift, this kit adapts to your modifications. For lifts exceeding 6 inches, reach out to us for custom setup recommendations.

Dual-Stage Powder Coating for Maximum Durability

All components undergo a rigorous two-stage powder coating process for unmatched corrosion resistance. A zinc primer base coat forms a protective barrier against rust, moisture, and debris, while a custom top coat finish is available in 10 color options, allowing you to personalize your build while adding an extra layer of durability.

Proudly Made in the USA

Manufactured in our Orem, UT facility, the Camp Series Complete Rear Kit is precision-crafted for quality, performance, and long-term reliability. By choosing CORE 4X4, you support American manufacturing, local sourcing, and strict quality control.

Optional Hardware Upgrade

This kit is designed for direct installation using factory hardware. For those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a seamless and secure installation.


  • Vehicle Fitment: Ford Bronco 21+ – Precision-engineered for all trims to enhance suspension stability, handling, and off-road performance.

  • CORE Advantage: Eliminates axle misalignment, improves ride quality, and enhances articulation with a hybrid bushing and Johnny Joint design.

  • Adjustability: Designed to accommodate 0–6” lifts, allowing precise pinion angle correction and axle centering for improved handling and suspension performance.

  • Construction: Made from heavy-duty 5/16” wall DOM tubing with polyurethane bushings and Johnny Joints for durability, comfort, and off-road flexibility.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

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!

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

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.
