Details

Core 4x4's Cruise Series rear adjustable track bar replaces the worn factory track bar on the GMC Yukon Denali (2001–2006). 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
  • You break it, we 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-DEN-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)
  • GMC Yukon / Yukon XL 1500 (2000–2006)
  • GMC Yukon Denali / XL Denali (2001–2006)
  • Cadillac Escalade / ESV / EXT (2002–2006)
  • 1500-series only. Does NOT fit 2500-series HD.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

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.

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.
