Details
Core 4x4's Crawl Series rear upper control arms replace the worn factory stamped-steel arms on the Chevy Suburban 1500 (2007–2014). The factory arms use soft rubber bushings and a fixed length, so there's no way to correct pinion angle after a lift or leveling kit. These Core 4x4 arms are a serious step up: DOM steel tubing and forged Rock Jock Johnny Joints at both ends for maximum articulation, with adjustable length to set rear pinion angle back to spec.
Includes: Rear upper control arms (pair); mounting hardware (bolts, nuts, and washers).
Specs:
- Tubing — 1.5 in. o.d. × 5/16 in. wall DOM steel
- Joints — forged Rock Jock Johnny Joints, both ends (double-threaded)
- Adjustable length — for 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.

- Hardware is included with your arms. If you ever need replacements down the road, the matching kit is available separately.
