Details
Core 4x4's Camp Series rear sway bar end links replace the worn factory links on the GMC Yukon Denali (2001–2006). The factory links use soft rubber bushings and are sized for stock ride height, so after a lift they sit at the wrong length and the sway bar can't keep the body flat the way it should. These Core 4x4 end links are a serious step up: 0.75 in. solid cold-rolled steel, a poly bushing at the sway-bar end, and a welded Rock Jock Johnny Joint at the frame end for added articulation, built to the exact length for your lift so the bar holds up under load.
Includes: Rear sway bar end links (pair); mounting hardware (bolts, nuts, and washers).
Specs:
- Material — 0.75 in. solid cold-rolled steel
- Ends — poly bushing at the sway-bar end, welded Rock Jock Johnny Joint at the frame end
- Built to length — for your selected lift size (stock–6 in., or custom), non-adjustable
- Made in the USA
- You break it, we replace it
- Wear items (bushings, joints) — covered for 18 months
Notes:
- Core 4x4 end links use a thru-bolt design that won't work with factory stud-and-nut hardware, so the install hardware — bolts, nuts, and washers — always ships in the box. If you ever need replacements down the road, the matching kit is available separately.
- Doing a lift? The 7-piece full rear kit (CMP-G-800-DEN-RK7-Z55) does the entire rear suspension in one order.
Parts:
- Poly bushing — BSH-TBBH-CB, 12mm bolt (1 per link, 2 for the pair).
- Johnny Joint rebuild kit — CE-9112NRK, welded frame end (1 per link, 2 for the pair).
- Replacement hardware kit — CMP-G-800-REL2-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.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's!
They appear to be so well built and just a true quality product.
Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned.
Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

I want to take the time to share my experience with Core 4x4.
I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship.
I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies.
The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle.
My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none.
I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers.
Thank you Korby, and thank you Core 4x4!

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 ! ! !

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!

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!

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

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.

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

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.
