Details
Core 4x4's Camp Series rear upper control arms replace the worn factory stamped-steel arms on the Chevy Suburban 1500 (2000–2006). 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 — Standard or Autoride (Z55): Select at checkout. Z55 trucks have factory rear air leveling; the Autoride version includes the ride-height sensor mounting tab on both rear upper arms. If you're not sure which you have, check the RPO sticker in the glove box for a Z55 code.
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-SUB-RS4) 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)

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

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!

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 :) .

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me.
As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a
Difference from the cheap oem rear control arms to these and the pan hard bar.
Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop!
Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

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.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!
