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 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. 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
- You break it, we 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-DXL-RK7-Z55) adds the rear sway bar end links to finish the rear.

- 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).
