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.

What’s Included in the Kit?

  • Cruise Series Front Track Bar (CRS-J-WJ-FTB1)

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.

In Conclusion

The Cruise Series Front Track Bar is the ultimate fix for death wobble and steering instability in your Jeep Grand Cherokee WJ. When paired with the Cruise Series Front Control Arm Set (CRS-J-WJ-FS4), you gain a fully optimized suspension system that restores stability, eliminates wobble, and enhances overall handling.

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

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

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!!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store
