Optimize Performance and Enhance Comfort

Upgrade both your on-road drivability and off-road capability with the Cruise Series Complete Rear Kit, designed specifically for Jeep Grand Cherokee WK model years 2005-2010. This all-in-one kit enhances axle alignment, corrects pinion angles, and eliminates rear-end instability, delivering a significant improvement over stock suspension components.

Key Features and Benefits

  • Enhanced Strength Durability – Heavy-duty steel tubing ensures superior longevity compared to factory parts.
  • Optimized Adjustability – Designed to accommodate 0 to 6 inches of lift, allowing precise pinion angle correction and rear axle re-centering.
  • Tapered Polyurethane Bushings – Provides better responsiveness, smoother articulation, and reduced vibrations.
  • Recommended Pairing – To complete your suspension upgrade, pair this kit with high-performance shocks and springs to build a fully optimized lift kit.

Total Rear-End Stability Adjustability

Lifting your Jeep can disrupt suspension geometry, leading to rear-end wandering, improper pinion angles, and premature drivetrain wear. Our adjustable control arms and rear track bar work together to re-center your axle, correct driveline angles, and restore handling precision. With the ability to fine-tune your suspension setup, this kit ensures optimal performance whether you're navigating rugged trails or cruising on the highway.

Two-Stage Powder Coating for Maximum Durability

To extend product life and enhance corrosion resistance, all components undergo a two-stage powder coating process. A zinc primer base coat provides rust protection, followed by a durable topcoat available in 10 colors, allowing you to customize your suspension setup.

Made in the USA

Proudly manufactured in Orem, UT, using locally sourced materials. We maintain strict quality control to ensure our products outperform and outlast stock components.

Optional Hardware Upgrade

This kit is designed for a seamless installation using factory hardware. However, for those dealing with rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, to make installation effortless.


  • Vehicle Fitment: Jeep Grand Cherokee WK 05-10 – Enhances rear-end stability, optimizes axle alignment, and improves drivability by correcting pinion angles, ensuring smooth handling both on and off-road.

  • CORE Advantage: Corrects rear suspension geometry to eliminate wandering, reduce driveline vibrations, and restore handling precision, offering a superior performance upgrade over factory components.

  • Adjustability: Fully adjustable for lifts from 0 to 6 inches, allowing precise axle re-centering, pinion angle correction, and improved suspension geometry for enhanced control.

  • Construction: Built from heavy-duty steel tubing with tapered polyurethane bushings, providing superior durability, smoother articulation, and long-lasting reliability over stock parts.

  • 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.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

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.

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!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

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.
