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!

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

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.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.
