Details

Core 4x4's Camp Series rear upper control arms replace the 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 correct pinion angle after a lift or leveling kit. These Core 4x4 arms are a serious step up: DOM steel tubing, a poly bushing at the fixed end, and a forged Rock Jock Johnny Joint at the adjustable end for increased articulation, with adjustable length to set rear pinion angle back to spec.

Includes: Rear upper control arms (pair); mounting hardware (bolts, nuts, and washers).

Specs:

  • Tubing — 1.5 in. o.d. × 5/16 in. wall DOM steel
  • Joints — poly bushing at the fixed end, forged Rock Jock Johnny Joint at the adjustable end
  • Adjustable length — for 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 4-piece rear set (CMP-G-800-EXT-RS4-Z55) adds the matching lower arms to replace all four rear arms in one job.

Parts:

  • Poly bushing — BSH-UPBH-CB, 9/16-in. bolt (1 per arm, 2 for the pair).
  • Forged Rock Jock Johnny Joint — CE-9112N-22 (1 per arm, 2 for the pair).
  • Replacement hardware kit — CMP-G-800-RU2-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!

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!
