Details
Core 4x4's Crawl Series 5-piece rear suspension kit replaces all four worn factory stamped-steel control arms and the worn factory track bar on the Chevy Suburban 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. These Core 4x4 parts are a serious step up: DOM steel tubing and Rock Jock Johnny Joints at both ends of every arm and the track bar for maximum articulation, with adjustable length to set rear axle alignment, side-to-side centering, and pinion angle back to spec.
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 — 1.5 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 — Rock Jock Johnny Joints, both ends (every arm and the track bar)
- Adjustable length — arms and track bar
- 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 — 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.
- Running a lift? The 7-piece full rear kit (CRL-G-800-SUB-RK7) adds the rear sway bar end links to finish the rear.
