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 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. 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-ESV-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)

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.
