Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

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.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

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.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!
