Details

Core 4x4's Cruise Series 5-piece rear suspension kit replaces all four worn factory stamped-steel control arms and the worn factory track bar on the GMC Yukon Denali (2001–2006). 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. These Core 4x4 parts are a serious step up: heavier steel construction, fresh poly bushings, and adjustable length to set rear axle alignment, side-to-side centering, and pinion angle back to spec.

They're also built to grow with your truck. When you want more articulation later, each adjustable end — on all four arms and the track bar — accepts the same forged Rock Jock Johnny Joints our Camp parts use, so you can upgrade in place without replacing the whole kit.

Includes: Rear upper control arms (pair), rear lower control arms (pair), and the rear adjustable track bar; mounting hardware (bolts, nuts, and washers).

Specs:

  • Upper arms — 1.625 in. o.d. × 3/16 in. wall steel
  • Lower arms — 1.875 in. o.d. × 3/16 in. wall steel
  • Track bar — 1.5 in. o.d. × 5/16 in. wall DOM steel
  • Bushings — poly, all ends
  • Adjustable length — arms and track bar
  • Lift range — 0–6 in.
  • 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.
  • Future upgrade: each adjustable end accepts a forged Rock Jock Johnny Joint — the rear uppers take CE-9112N-22 (two), the rear lowers take CE-9114 (two), and the track bar takes CE-9112N-22 (one).
  • Running a lift? The 7-piece full rear kit (CRS-G-800-DEN-RK7-Z55) adds the rear sway bar end links to finish the rear.

Parts:

  • Upper poly bushings — BSH-UPBH-CB, 9/16-in. bolt (2 per upper arm, 4 for the upper pair).
  • Lower poly bushings — BSH-LOBH-CB, 9/16-in. bolt (2 per lower arm, 4 for the lower pair).
  • Track bar poly bushings — BSH-UPBH-CB, 9/16-in. bolt (1 per end, 2 for the track bar).
  • Replacement hardware kit — CRS-G-800-RK5-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.

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.

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

Great product for a good price. Customer service is top notch, I had an issue which was self cause and Core 4x4 helped me out even though it was my own fault. Would definitely recommend and use them again.

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.

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.

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 :) .

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 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!
