What Peterson Spring does

Peterson Spring, operating as Peterson American Corporation (PAC), is the largest privately held spring manufacturer in North America, founded in 1914 in Detroit and now headquartered in Southfield, Michigan. The company designs, manufactures, and supplies engineered metal components—compression, extension, torsion, die, and engine valve springs; PACALOY® and PAC-LIFE die/valve springs; snap and retaining rings; wire forms; clips and constant-tension hose clamps (producing over 66 million per year); metal stampings up to 250 tons with 48x96-inch die beds; and design-to-delivery sub-assemblies—using CNC coiling, gas nitriding, Nano Peen™ surface enhancement, and proprietary heat-treatment regimes validated in in-house metallurgical and dynamics laboratories. Peterson Spring serves 450+ customers across 48 countries from 12-13 facilities in the United States, Canada, Mexico, and the United Kingdom (via Peterson Spring Europe Ltd.), with additional capability provided by a Specialty Products Division for prototypes and short runs and a PAC Racing Springs sub-brand for the motorsport aftermarket.

The business is monetized through custom-quote, project-based hardware sales to OEM and Tier-1 customers in automotive (primary), aerospace/defense, agriculture, construction, consumer products, medical/healthcare, and recreational vehicles, supplemented by prototype/small-run professional services revenue from the Specialty Products Division and packaging/secondary operations revenue from a Three Rivers Packaging-Distribution unit. Go-to-market is sales-led with direct enterprise engagement, master distribution through Signature Engineered Solutions (North America, launched October 2019) and TR Fastenings Ltd. (Europe), and supporting presence at industry trade shows and via SMI/OESA/HDMA/SME/British American Business Council affiliations. The company has been owned by private equity firm MiddleGround Capital since 2019.

Brands

• PAC Racing Springs: Aftermarket and racing manufacturer division specializing in engine valve springs, suspension springs, and chassis suspension systems. Headquartered in Southfield, Michigan with a facility in Mooresville, North Carolina.

Products and services

• Compression, Extension, and Torsion Springs Core spring configurations manufactured for automotive, aerospace, industrial, and consumer applications. Compression springs are the most common; extension springs store energy and exert pulling force; torsion springs apply torque or store rotational energy.
• PAC-LIFE Die Springs High-force compression springs designed for extreme temperature applications in die-stamping and injection-molding operations. Available in Standard Inch, ISO Inch, and ISO Metric Series with duty ratings from Light to Extra Heavy. Proven to last significantly longer than other springs due to superior design.
• Engine Valve Springs Valve springs for engines, fuel injectors, latch mechanisms, torque converters, and clutch assemblies. PACALOY Valve Springs use high-strength super-clean alloy and serve as the standard in professional racing.
• Large Wire Diameter Springs Heavy compression, extension, and torsion springs manufactured using CNC coiling technology for large wire diameters. Used in automotive suspension, agricultural equipment, construction, and industrial equipment applications.
• Clips and Hose Clamps Metal clips, clamps, and constant tension hose clamps manufactured from alloy, stainless steel, cold rolled carbon steel, and galvanized materials. Peterson produces over 66 million hose clamps annually and manages the largest stock of dual wire clamps in North America.
• Rings (Snap Rings, Retaining Rings, Transmission Rings) Coiled snap/retaining rings with inner diameters from .062 inches to 72 inches (1.57mm to 1830mm), and transmission rings engineered specifically for powertrain systems. Coiled rings offer cost advantages over stamped rings.
• Stampings Metal stampings with press capacities up to 250 tons and die bed sizes up to 48x96 inches. Specializes in progressive die operations for high carbon clips, brackets, and precision metal parts using hot and cold finished steel, aluminum, and stainless steel.
• Sub-Assemblies Design-to-delivery assembly services including springs assembled with bearings, dampers, caps, bolts, buttons, and stampings welded to wire forms. Also offers secondary operations such as painting, striping, packaging, and sequencing.
• Wire Forms Wire forms bent into engineered shapes using round wire or strip material. Includes torque rods, frames, automotive seat frames, air bag door frames, border wires, and headrest frames for various industrial applications.
• Specialty Products Division (SPD) Small order and prototype spring, wire form, and spring clip production division handling wire sizes from 0.010 to 0.750 inches and snap rings up to 120 inches diameter. Offers wire shaping, piercing, bending, coining, grinding, packaging, assembly, and painting services with no minimum order requirements.
• PAC Racing Springs Aftermarket and racing manufacturer division specializing in engine valve springs, suspension springs, and chassis suspension systems. Located in Mooresville, North Carolina with a chassis product development center serving professional and amateur racing customers.
