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!

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

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.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.
