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)

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

Excellent, strong, and durable products—perfect for both on-road and off-road applications. The customer service is outstanding—friendly, knowledgeable, and extremely helpful with understanding installation and ensuring I got exactly what I needed. I would definitely order again. Top-notch company with high-quality products made right here in the U.S.A.

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

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.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.
