PROP SHAFT SUPPLY INC

Prop Shaft Supply Inc. specializes in the design, manufacturing, and supply of critical mechanical power transmission components for defense and military vehicle platforms. Their core capabilities center on the production of propeller shafts, universal joints, yokes, and companion flanges—precision-engineered parts essential to drivetrain systems in tactical and heavy-duty vehicles. The company demonstrates deep technical expertise in high-torque, high-vibration environments, adhering to military specifications for durability, material integrity, and dimensional accuracy. Their specialization in driveline components for armored and expeditionary platforms positions them as a trusted supplier of mission-critical hardware that operates under extreme operational conditions. The contractor maintains a consistent relationship with the Department of Defense, delivering components used across land-based combat, logistics, and mobility systems. Their work supports maintenance, repair, and overhaul programs for ground vehicle fleets, with a focus on sustaining legacy and current-generation military platforms through direct supply of replacement and repair parts. While DLA Land and Maritime appears as a secondary customer, their solicitations indicate engagement in indefinite delivery contract pathways, suggesting alignment with long-term sustainment strategies. Prop Shaft Supply Inc. operates primarily within NAICS 336350 (Motor Vehicle Transmission and Power Train Parts Manufacturing) and 333613 (Mechanical Power Transmission Equipment Manufacturing), focusing on the defense segment of the commercial drivetrain market. Their vertical specialization lies in heavy-duty, non-commercial powertrain components, distinguishing them from general automotive suppliers. As a small business structured as a 2L entity based in Delavan, Wisconsin, the company lacks federal certifications but maintains a focused geographic footprint in the Midwest industrial corridor, serving as a niche supplier to U.S. defense logistics networks with proven reliability in delivering precision-engineered transmission components.
