Details

Core 4x4's Crawl Series 5-piece rear suspension kit replaces all four worn factory stamped-steel control arms and the worn factory track bar on the GMC Yukon 1500 (2000–2006). The factory parts use soft rubber bushings and a fixed length, so there's no way to re-align the rear axle, recenter it side-to-side, or correct pinion angle after a lift or leveling kit. These Core 4x4 parts are a serious step up: DOM steel tubing and Rock Jock Johnny Joints at both ends of every arm and the track bar for maximum articulation, with adjustable length to set rear axle alignment, side-to-side centering, and pinion angle back to spec.

Includes: Rear upper control arms (pair), rear lower control arms (pair), and the rear adjustable track bar; mounting hardware (bolts, nuts, and washers).

Specs:

  • Upper arms — 1.5 in. o.d. × 5/16 in. wall DOM steel
  • Lower arms — 1.75 in. o.d. × 5/16 in. wall DOM steel
  • Track bar — 1.5 in. o.d. × 5/16 in. wall DOM steel
  • Joints — Rock Jock Johnny Joints, both ends (every arm and the track bar)
  • Adjustable length — arms and track bar
  • Lift range — 0–6 in. and up
  • Made in the USA
  • You break it, we replace it
  • Wear items (bushings, joints) — covered for 18 months

Suspension Type — Standard or Autoride (Z55): Select at checkout. Z55 trucks have factory rear air leveling; the Autoride version includes the ride-height sensor mounting tab on both rear upper arms. If you're not sure which you have, check the RPO sticker in the glove box for a Z55 code.

Notes:

  • Hardware is included with your kit. If you ever need replacements down the road, the matching kit is available separately.
  • Running a lift? The 7-piece full rear kit (CRL-G-800-YUK-RK7) adds the rear sway bar end links to finish the rear.

Parts:

  • Upper forged Rock Jock Johnny Joint, right-hand — CE-9112N-22 (1 per upper arm, 2 for the upper pair).
  • Upper forged Rock Jock Johnny Joint, left-hand — CE-9112NL-22 (1 per upper arm, 2 for the upper pair).
  • Lower forged Rock Jock Johnny Joint, right-hand — CE-9114 (1 per lower arm, 2 for the lower pair).
  • Lower forged Rock Jock Johnny Joint, left-hand — CE-9114L (1 per lower arm, 2 for the lower pair).
  • Track bar forged Rock Jock Johnny Joint, right-hand — CE-9112N-22 (1 for the track bar).
  • Track bar forged Rock Jock Johnny Joint, left-hand — CE-9112NL-22 (1 for the track bar).
  • Replacement hardware kit — CRL-G-800-RK5-HWK.

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.

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

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.

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.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!
