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.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Great company! I have used there products consistently with no complaints with quality you can see and feel. From my experience, their customer service is also amazing. Core 4x4 has no issues standing behind their already amazing products and will quickly and professionally solve issues may they arise. I will continue to be a customer.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

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.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

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.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.
