Details

Core 4x4's Crawl Series 7-piece full rear suspension kit replaces all four worn factory stamped-steel control arms, the worn factory track bar, and the worn factory sway bar end links on the Cadillac Escalade EXT (2002–2006). 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 — and the end links sit at the wrong length, so the sway bar can't keep the body flat the way it should. 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 — plus solid cold-rolled-steel end links with welded Rock Jock Johnny Joints at both ends, built to the exact length for your lift to hold up to hard off-road use.

Includes: Rear upper control arms (pair), rear lower control arms (pair), the rear adjustable track bar, and the rear sway bar end links (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
  • Track bar — 1.5 in. o.d. × 5/16 in. wall DOM steel
  • Joints (arms & track bar) — Rock Jock Johnny Joints, both ends
  • End links — 0.75 in. solid cold-rolled steel; welded Rock Jock Johnny Joints, both ends; built to length for your selected lift size (stock–6 in., or custom), non-adjustable
  • Adjustable length — arms and track bar
  • 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 kit. If you ever need replacements down the road, the matching kit is available separately.
  • This is the complete rear suspension package — pair it with quality rear shocks and a front leveling or lift kit to balance the truck out.

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).
  • End-link Johnny Joint rebuild kit — CE-9112NRK, welded both ends (1 per end, 4 for the pair).
  • Replacement hardware kit — CRL-G-800-RK7-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)

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 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.

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.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

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!

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.
