Northern Illinois Auto Supply Connects Chicago and the Heartland
Rockford's automotive sector is anchored by the Stellantis Belvidere Assembly Complex just east of the city, which has produced Jeep Cherokee models and is slated for EV-related investment. Rivian's Normal, IL assembly plant is within the supply corridor, and the region's deep CNC machining base — shaped by decades of aerospace and fastener manufacturing — serves Tier 2 automotive programs across northern Illinois.
RivCut gives Rockford automotive teams instant quoting, fast-turn production machining, and the PPAP documentation Stellantis and Tier 1 quality systems demand.
