Details

Core 4x4's Crawl Series 4-piece rear control arm set replaces all four worn factory stamped-steel arms on the Cadillac Escalade EXT (2002–2006). 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-EXT-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)

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 ! ! !

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

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.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.
