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.
