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.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.
