Eliminate Death Wobble and Maximize Stability

If you've experienced death wobble, you know how unsettling it can be. The Cruise Series Front Track Bar is a critical upgrade for Jeep Grand Cherokee WJ (1999-2004) owners looking to eliminate steering instability, axle shift, and suspension shake.

Death wobble is often caused by loose, worn-out suspension components, improper caster angle, and a weak factory track bar. This heavy-duty, adjustable track bar corrects axle alignment, eliminating excessive movement that contributes to the problem.

For a complete solution, we highly recommend pairing this track bar with the Cruise Series Front Control Arm Set (CRS-J-WJ-FS4). Together, these components provide proper caster correction and precise axle centering, addressing all factors contributing to death wobble.

Key Features and Benefits

  • Eliminates Death Wobble – A strong, properly aligned front track bar eliminates the uncontrolled side-to-side oscillations that cause death wobble.
  • Optimized Axle Centering – Keeps your front axle perfectly aligned, preventing shifting that contributes to instability.
  • Adjustability for Lifted Vehicles – Designed to accommodate lifts from 2 to 6 inches, ensuring proper axle alignment and geometry.
  • Heavy-Duty Construction – Built from high-strength steel tubing, ensuring superior durability and longevity over factory components.
  • High-Grade Polyurethane Bushings – Provides smoother operation and enhanced responsiveness, outperforming factory rubber bushings.
  • Recommended Pairing – For complete death wobble elimination, pair with the Cruise Series Front Control Arm Set (CRS-J-WJ-FS4) to correct caster angle and axle alignment simultaneously.

How This Track Bar Eliminates Death Wobble

Death wobble occurs when suspension components allow excessive, uncontrolled movement, particularly in lifted vehicles. The Cruise Series Front Track Bar prevents axle deflection by keeping the front axle centered under the vehicle, even under extreme conditions.

However, death wobble isn’t just about the track bar—improper caster angles due to lifted suspension also play a major role. That’s why we highly recommend pairing this track bar with our Cruise Series Front Control Arm Set (CRS-J-WJ-FS4). The control arms correct caster, while the track bar ensures solid axle positioning, providing a full solution to eliminate wobble and instability.

Two-Stage Powder Coating

To ensure maximum durability and corrosion resistance, our track bars undergo a two-stage powder coating process: Zinc primer base coat prevents rust and corrosion.  Durable top coat in your choice of 10 colors, allowing for customization and added protection.

Made in the USA

The Cruise Series Front Track Bar is proudly manufactured in Orem, UT, using locally sourced materials. By maintaining full control over our production process, we guarantee top-tier craftsmanship and unmatched reliability.

Optional Hardware Upgrade

This track bar is designed to install using factory hardware. However, if your hardware is rusted or difficult to remove, we offer optional Grade 8 hardware kits, available separately, for a seamless installation.

Upgrade today and drive with confidence, knowing your suspension is built to handle anything the road or trail throws at it!

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 just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

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.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.
