Details
Core 4x4's Crawl Series 4-piece rear control arm set replaces all four worn factory stamped-steel arms on the Chevy Avalanche 1500 (2002–2006). 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 and Rock Jock Johnny Joints at both ends of every arm for maximum 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 — Rock Jock Johnny Joints, both ends (every arm)
- 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 — 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 arms. If you ever need replacements down the road, the matching kit is available separately.
- Running a lift? The 5-piece rear kit (CRL-G-800-AVA-RK5) adds the adjustable track bar to recenter the axle side-to-side.
