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.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

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!

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you 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!!

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.
