ALCO Spring

What ALCO Spring does

ALCO Spring (legal entity Alco Spring Industries, Inc.), founded in 1908 and now operating as a brand under A. Stucki Company, manufactures custom hot wound steel springs for the rail, industrial, and automotive markets from a 150,000 sq. ft. integrated production facility in Chicago Heights, Illinois. The company produces coiled springs ranging from 0.4 lbs to 900 lbs, with order sizes from individual units to hundreds of thousands, manufactured to ASTM A-125 and AAR M-114 standards. Its product portfolio is organized around seven application verticals — freight car, locomotive, agricultural, energy (oil, gas, nuclear), mining, snow removal/track sensors, and vehicle suspension — with named historical customers including ALCO, GE Transportation, and EMD (Electro-Motive Division of General Motors).

The business is structured around direct B2B enterprise sales under the A. Stucki umbrella, supplemented by an e-commerce storefront on stucki.com. ALCO differentiates through AAR M-1003 and ISO 9001 certifications, in-house inspection capabilities (static/dynamic load testing, magnetic particle, ultrasonic, hardness, shotpeen, fatigue), and a service commitment to respond to customer phone inquiries within three hours and visit customer facilities within 24 hours. Revenue is generated from one-time direct sales of custom-engineered and standard catalog springs on a quote-based pricing model; financial performance is not publicly disclosed. Marketing reaches customers through the A. Stucki Company website, social media channels, industry events such as ASLRRA, and an email newsletter. The company does not maintain any subsidiaries, has no disclosed leadership team, and operates as a wholly-owned strategic brand within the A. Stucki portfolio.
