Warranty facts, not marketing language.

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

Eliminate Axle Shift Reduce Death Wobble for Ultimate Stability

Death wobble is one of the most concerning issues Jeep owners face. It occurs when your front suspension and steering components fall out of alignment, causing the steering wheel to shake violently at high speeds or after hitting bumps. Loose or worn-out track bars, improper caster angles, and misaligned axles are the most common causes.

Our Cruise Series Front Track Bar is designed to eliminate axle shift, maintain proper suspension geometry, and improve steering response, reducing the likelihood of death wobble and providing the stability your Jeep Wrangler JL needs.

When paired with our Cruise Series Front Control Arm Set (CRS-J-JL-FS4), this combination offers precise alignment correction, caster adjustment, and axle centering, creating a complete front-end suspension solution.

What’s Included in the Kit?

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

Key Features Benefits

  • Prevents Axle Shift Steering Instability – Re-centers the front axle after lifting your Jeep, reducing suspension stress and preventing unwanted steering pull.
  • Reduces Death Wobble – Helps eliminate one of the primary causes of death wobble by keeping your front axle locked in place, especially when paired with adjustable front control arms for caster correction.
  • Heavy-Duty Construction – Built from 1.5" OD .313 Wall DOM tubing, this track bar withstands extreme off-road conditions while ensuring smooth operation on the road.
  • Precision-Adjustable for Lifted Jeeps – Compatible with 0 to 6 inches of lift, allowing for on-vehicle fine-tuning to keep suspension components aligned. For lifts over 6 inches, contact us for additional options.
  • Recommended Pairing for Maximum Stability – Combine with our Cruise Series Front Control Arm Set (CRS-J-JL-FS4) to correct caster, re-center the axle, and reduce death wobble risk.

How This Track Bar Helps Reduce Death Wobble

Death wobble is caused by loose, worn, or misaligned suspension components, leading to uncontrollable vibrations. A factory track bar is not designed to handle lifted suspensions, which can cause the front axle to shift out of place, making steering feel loose and unstable.

By installing our adjustable Front Track Bar, you lock the front axle in its proper position, preventing it from wandering or shifting under load. This reduces suspension oscillations that can trigger death wobble. For the best results, pairing it with adjustable front control arms ensures proper caster correction, eliminating another major cause of steering instability.

Durable Two-Stage Powder Coating

Each track bar undergoes a two-stage powder coating process: Zinc Primer Base Coat  Creates a strong foundation for rust and corrosion resistance. Durable Top Coat – Available in 10 color options, allowing you to customize your Jeep’s look while adding extra protection.

Proudly Made in the USA

Manufactured in Orem, UT, this track bar is built to the highest standards. By maintaining full control over production, we ensure each component meets rigorous quality and durability standards.

Optional Hardware Upgrade

The Cruise Series Front Track Bar reuses your Jeep’s factory mounting hardware for installation. If your existing bolts are rusted, worn, or difficult to remove, we offer optional Grade 8 hardware kits separately to ensure a secure and hassle-free installation. Upgrading your hardware can provide added durability and peace of mind, especially for off-road and lifted setups.

In Conclusion

If you’re experiencing wandering steering, axle misalignment, or even signs of death wobble, upgrading to our Cruise Series Front Track Bar is an essential step in restoring stability and control.

Pair it with our Cruise Series Front Control Arm Set to fine-tune caster angle and completely eliminate the root causes of death wobble. Upgrade today for a smoother, more controlled, and more confident driving experience!

Notes: Some (not all) factory axle mounts need to be "clearanced" to accept our larger bar. If needed, it is only a minor amount of trimming to be done. Please see our Youtube channel for a video addressing this.

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 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!

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

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.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

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!
