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!

 

  • Vehicle Fitment: Jeep Grand Cherokee WJ 99-04 – Corrects axle alignment, prevents front-end instability, and helps eliminate death wobble for a more controlled and predictable driving experience.

  • CORE Advantage: Help eliminate death wobble by keeping the front axle centered, reducing side-to-side oscillations, and improving overall suspension stability for lifted vehicles.

  • Adjustability: Fully adjustable to accommodate lift heights from 2 to 6 inches, ensuring proper axle positioning and suspension geometry.

  • Construction: Built from high-strength steel tubing with reinforced bushings, providing extreme durability, improved responsiveness, and long-term performance over factory components.

  • 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.

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.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

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.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.
