Details

Core 4x4's Cruise 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 Cadillac Escalade ESV (2003–2006). 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: heavier steel construction, fresh poly bushings, and adjustable length to set rear axle alignment, side-to-side centering, and pinion angle back to spec — plus solid cold-rolled-steel end links built to the exact length for your lift, so the sway bar does its job again.

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 those ends in place without replacing the arms or track bar.

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 — 1.625 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
  • End links — 0.75 in. solid cold-rolled steel; built to length for your selected lift size (stock–6 in., or custom), non-adjustable
  • Bushings — poly, all ends
  • 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.
  • 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).
  • 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 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).
  • End-link poly bushings — BSH-TBBH-CB, 12mm bolt (2 per link, 4 for the pair).
  • Replacement hardware kit — CRS-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)
  • Cadillac Escalade / ESV / EXT (2002–2006)
  • 1500-series only. Does NOT fit 2500-series HD.

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!!!

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 wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

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.
