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.

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.

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.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

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!!

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

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!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

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.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.
