Details

Core 4x4's Crawl Series 4-piece rear control arm set replaces all four worn factory stamped-steel arms on the GMC Yukon Denali (2001–2006). The factory arms use soft rubber bushings and a fixed length, so there's no way to re-align the rear axle or correct pinion angle after a lift or leveling kit. These Core 4x4 arms are a serious step up: DOM steel tubing and Rock Jock Johnny Joints at both ends of every arm for maximum articulation, with adjustable length to set rear axle alignment and pinion angle back to spec.

Includes: Rear upper control arms (pair) and rear lower control arms (pair); 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
  • Joints — Rock Jock Johnny Joints, both ends (every arm)
  • Adjustable length — for rear-axle alignment and pinion-angle correction
  • Lift range — 0–6 in. and up
  • Made in the USA
  • Lifetime warranty — bend it or break it, we'll replace it
  • Wear items (bushings, joints) — covered for 18 months

Suspension Type — Factory Autoride (Z55): Chances are, your truck came with rear Autoride (Z55) from the factory — GM's air-leveling system. This part is built to match: the ride-height sensor mounting tab is included on both rear upper arms, so your factory sensors bolt right back on. Converted to coil springs — or never had air ride at all? No problem — everything fits and works exactly the same; the sensor tabs just go unused.

Notes:

  • Hardware is included with your arms. If you ever need replacements down the road, the matching kit is available separately.
  • Running a lift? The 5-piece rear kit (CRL-G-800-DEN-RK5-Z55) adds the adjustable track bar to recenter the axle side-to-side.

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).
  • Replacement hardware kit — CRL-G-800-RS4-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.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

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.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.
