Details

Replacement install hardware for the Core 4x4 7pc Full Rear Suspension Kit on GMT900 rear suspension (2007–2014). Every Core 4x4 product already ships with this hardware in the box — this $75 kit is the standalone replacement value, for when you need a fresh set (bolts lost or damaged during install, a powder-coat refresh, or a warranty replacement). The hardware is USA-sourced Grade 8 / Class 10.9; it is the same across the Cruise, Camp, and Crawl series apart from the fender washers noted below.

Includes:

  • 14 bolts total (6× 9/16 in. × 3.5 in. + 4× 9/16 in. × 4 in. + 2× M12 × 70 mm + 2× M12 × 65 mm)
  • 12 standard nuts
  • 2 nut tabs (upper-arm frame-side mount)
  • 26 standard washers
  • 2× fender washers (sway-bar end)

Note: Shim washers are not part of this hardware kit. When your series needs them (Camp and Crawl), they ship with the arms or track bar themselves.

Fender washers: included on Cruise and Camp (2, at the sway-bar end); Crawl uses a welded Johnny Joint there and needs none.

Fits:

  • Chevy Tahoe (2007–2014)
  • Chevy Suburban 1500 (2007–2014)
  • Chevy Avalanche (2007–2013)
  • GMC Yukon / Yukon XL 1500 (2007–2014)
  • GMC Yukon Denali / XL Denali (2007–2014)
  • Cadillac Escalade / Escalade ESV (2007–2014)
  • Cadillac Escalade EXT (2007–2013)
  • 1500-series only. Does NOT fit 2500-series HD.

Universal across all ten GMT900 trucks — the hardware is the same for every model.

Made in the USA. You break it, we replace it.

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

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.

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.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

Korby was a great help with getting me a set of leaf springs for my Cherokee. Great customer service and an awesome product all made in the USA. Proud to support and rock their parts on my vehicle. 👍 …

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.
