Details
Core 4x4's Cruise Series rear lower control arms replace the 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 after a lift or leveling kit. These Core 4x4 arms are a serious step up: heavier steel construction, fresh poly bushings, and adjustable length to set rear axle alignment back to spec.
They're also built to grow with your truck. When you want more articulation later, the adjustable end accepts the same forged Rock Jock Johnny Joint our Camp lower arms use, so you can upgrade in place without replacing the whole arm.
Includes: Rear lower control arms (pair); mounting hardware (bolts, nuts, and washers).
Specs:
- Tubing — 1.875 in. o.d. × 3/16 in. wall steel
- Bushings — poly, both ends
- Adjustable length — for rear-axle alignment
- 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
Notes:
- Hardware is included with your arms. 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 (CE-9114) — two for the pair.
- Running a lift? The 4-piece rear set (CRS-G-800-DXL-RS4-Z55) adds the matching upper arms to replace all four rear arms in one job.
Parts:
- Poly bushings — BSH-LOBH-CB, 9/16-in. bolt (2 per arm, 4 for the pair).
- Replacement hardware kit — CRS-G-800-RL2-HWK.
