Product Details

Details

Core 4x4's Camp 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 GMC Yukon XL 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 — 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, a poly bushing at each fixed end, and a forged Rock Jock Johnny Joint at each adjustable end for increased 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 a welded Rock Jock Johnny Joint at the frame end, built to the exact length for your lift so the sway bar holds up under load.

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) — poly bushing at each fixed end, forged Rock Jock Johnny Joint at each adjustable end
  • End links — 0.75 in. solid cold-rolled steel; 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
  • 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 poly bushing — BSH-UPBH-CB, 9/16-in. bolt (1 per upper arm, 2 for the upper pair).
  • Upper forged Rock Jock Johnny Joint — CE-9112N-22 (1 per upper arm, 2 for the upper pair).
  • Lower poly bushing — BSH-LOBH-CB, 9/16-in. bolt (1 per lower arm, 2 for the lower pair).
  • Lower forged Rock Jock Johnny Joint — CE-9114 (1 per lower arm, 2 for the lower pair).
  • Track bar poly bushing — BSH-UPBH-CB, 9/16-in. bolt (1 for the track bar).
  • Track bar forged Rock Jock Johnny Joint — CE-9112N-22 (1 for the track bar).
  • End-link poly bushing — BSH-TBBH-CB, 12mm bolt (1 per link, 2 for the pair).
  • End-link Johnny Joint rebuild kit — CE-9112NRK, welded frame end (1 per link, 2 for the pair).
  • Replacement hardware kit — CMP-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)

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

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!!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.
