Details
Core 4x4's Camp Series 4-piece rear control arm set replaces all four worn factory stamped-steel arms on the GMC Yukon XL Denali (2001–2006). The factory arms use soft rubber bushings and a fixed length, so there's no way to re-align the rear axle or correct pinion angle after a lift or leveling kit. These Core 4x4 arms 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 and pinion angle back to spec.
Includes: Rear upper control arms (pair) and rear lower control arms (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
- Joints — poly bushing at each fixed end, forged Rock Jock Johnny Joint at each adjustable end
- Adjustable length — for rear-axle alignment and pinion-angle correction
- Lift range — 0–6 in. and up
- 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 arms. If you ever need replacements down the road, the matching kit is available separately.
- Running a lift? The 5-piece rear kit (CMP-G-800-DXL-RK5-Z55) adds the adjustable track bar to recenter the axle side-to-side.
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).
