Solve Every Suspension Steering Issue with This Complete Upgrade

The Jeep Wrangler JK is an exceptional off-road platform, but its factory suspension system has well-documented weaknesses—including insufficient caster, wandering steering, following ruts in the road, and the dreaded death wobble. The Cruise Series 16-Piece Kit is designed to eliminate these issues entirely by replacing every major suspension and steering component with heavy-duty, fully adjustable upgrades that enhance handling, control, and overall drivability.

This all-inclusive kit provides everything needed to correct alignment, recenter axles, and optimize suspension geometry for lifts from 0 to 6 inches. Whether you’re daily driving or tackling the toughest trails, this kit delivers unmatched stability, precision, and durability.

Key Features and Benefits

  • Eliminates common JK suspension issues – Corrects insufficient caster, eliminates wandering, prevents following ruts in the road, and significantly reduces or eliminates death wobble.
  • Complete suspension steering overhaul – Replaces all major suspension and steering components with fully adjustable upgrades for precise alignment and axle positioning.
  • Adjustable for lifted vehicles – Control arms and track bars adjust to accommodate lifts from 0 to 6 inches, allowing for fine-tuned caster correction, axle centering, and suspension geometry optimization.
  • Build your own lift kit – Simply pair this kit with your preferred springs and shocks to create a custom lift kit that outperforms any off-the-shelf solution.
  • Ultimate steering precision stability – The 2.5-ton aluminum steering kit provides improved handling, eliminates play in the steering system, and enhances overall driving confidence.

Two-Stage Powder Coating for Maximum Protection

All components undergo a two-stage powder coating process for enhanced durability and corrosion resistance:

  • Zinc primer base coat for rust prevention and long-lasting protection.
  • Durable top coat available in 10 color options for personalized customization.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series 16-Piece Kit is built with American craftsmanship and locally sourced materials, ensuring the highest quality standards in every component.

Effortless Installation

Designed for a hassle-free, bolt-on installation using factory hardware. For those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately for a smoother setup.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.
