Details
Core 4x4's Camp 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 GMC Yukon XL 1500 (2000–2006). 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: 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, side-to-side centering, and pinion angle back to spec — plus solid cold-rolled-steel end links with a welded Rock Jock Johnny Joint at the frame end, built to the exact length for your lift so the sway bar holds up under load.
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 — 1.5 in. o.d. × 5/16 in. wall DOM steel
- Lower arms — 1.75 in. o.d. × 5/16 in. wall DOM steel
- Track bar — 1.5 in. o.d. × 5/16 in. wall DOM steel
- Joints (arms & track bar) — poly bushing at each fixed end, forged Rock Jock Johnny Joint at each adjustable end
- End links — 0.75 in. solid cold-rolled steel; poly bushing at the sway-bar end, welded Rock Jock Johnny Joint at the frame end; built to length for your selected lift size (stock–6 in., or custom), non-adjustable
- 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 — Standard or Autoride (Z55): Select at checkout. Z55 trucks have factory rear air leveling; the Autoride version includes the ride-height sensor mounting tab on both rear upper arms. If you're not sure which you have, check the RPO sticker in the glove box for a Z55 code.
Notes:
- Hardware is included with your kit. If you ever need replacements down the road, the matching kit is available separately.
- 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.
