Details

Core 4x4's Cruise Series rear adjustable track bar replaces the worn factory track bar on the Cadillac Escalade EXT (2002–2006). The factory bar uses soft rubber bushings and a fixed length, so there's no way to recenter the rear axle after a lift or leveling kit. This Core 4x4 track bar is a serious step up: DOM steel tubing, fresh poly bushings at both ends, and adjustable length to set the rear axle back to center.

It's also built to grow with your truck. When you want more articulation later, the adjustable end accepts the same forged Rock Jock Johnny Joint our Camp track bar uses, so you can upgrade in place without replacing the whole bar.

Includes: Rear adjustable track bar; mounting hardware (bolts, nuts, and washers).

Specs:

Tubing — 1.5 in. o.d. × 5/16 in. wall DOM steel
Bushings — poly, both ends
Adjustable length — to recenter the rear axle
Lift range — 0–6 in.
Made in the USA
Lifetime warranty — bend it or break it, we'll replace it
Wear items (bushings, joints) — covered for 18 months

Notes:

Hardware is included with your track bar. If you ever need replacements down the road, the matching kit is available separately.
Future upgrade: the adjustable end accepts a forged Rock Jock Johnny Joint (CE-9112N-22) — one for the track bar.
Running a lift? The 5-piece rear kit (CRS-G-800-EXT-RK5-Z55) adds the four rear control arms to re-align the rear axle in every direction.

Parts:

Poly bushings — BSH-UPBH-CB, 9/16-in. bolt (1 per end, 2 for the track bar).
Replacement hardware kit — CRS-G-800-RTB1-HWK.

Fits:

Chevy Tahoe (2000–2006)
Chevy Suburban 1500 (2000–2006)
Chevy Avalanche 1500 (2002–2006)

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

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!

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.

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.

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.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

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.
