About the company
Prop Shaft Supply Inc., a manufacturer of driveline components headquartered in Delavan, Wisconsin, competes as a prime contractor supplying universal joint yokes, propeller shafts, and companion flanges to the Defense Logistics Agency (DLA) Land and Maritime. The company operates as a wholly owned division of Machine Service, Inc., a small business Subchapter S corporation, and competes predominantly under Total Small Business set-asides on DLA contracts, with a minority of awards (roughly 40% of recent awards) also awarded through full and open competition.
The company's federal footprint is narrowly concentrated: the DLA Land and Maritime accounts for 359 of 413 prime awards (87% of prime contracts) worth $12.3 million in combined potential value, with the remainder split among Army acquisition support, general DLA, and one Marine Corps award. Prop Shaft Supply's capability profile is concrete and specialized—the source material names only three product categories across 236 awards under NAICS 336350 (Motor Vehicle Transmission and Power Train Parts Manufacturing): universal joint yokes (the dominant product), propeller shafts, and companion flanges. Recent representative prime awards include a $201,500 Total Small Business purchase order (January 2026) for 155 universal joint yoke components, a $72,311.58 delivery order for universal joint yokes under a single-award IDC (December 2025), and a $154,787.28 delivery order for propeller shaft components (June 2025). All orders are firm fixed-price; all place of performance is Delavan, Wisconsin.
Prop Shaft Supply sits on a portfolio of single-award Indefinite Delivery Contracts with the DLA Land and Maritime, each valued at $250,000 and designated as Total Small Business set-asides. The most recent IDC was awarded October 6, 2025, covering universal joint yokes with an estimated 10 orders per year; others cover propeller shafts, companion flanges, and related driveline parts, with ceiling values ranging from $250,000 to as high as $946,062 on older vehicles. The company's activity trajectory shows volatility—33 awards in 2022 declining to 14 in 2023, then recovering to 28 in 2024 and 31 in 2025—with six awards (combined potential value $315,000) facing ultimate completion within the next twenty-four months and therefore exposed to recompete.
Prop Shaft Supply also operates as a subcontractor to BAE Systems Land & Armaments L.P. on military vehicle production contracts. Recent sub-awards document material supply work for Bradley A4 follow-on production (M2A4 and M7A4 vehicles), Armored Multi-Purpose Vehicle (AMPV) production and test support, and Self-Propelled Howitzer System vehicle sets, with sub-awards dating from January 2024 through August 2025. These subcontracts supply driveline components—universal joint yokes and propeller shafts—into BAE Systems' vehicle assembly operations.
Prop Shaft Supply's customer concentration and set-aside posture create a narrow competitive moat: 94% of awards flow from two customer organizations (DLA Land and Maritime dominates the totals by far, with Army acquisition support accounting for most of the remainder), and the vendor's small business status restricts much of its direct-to-DLA work to set-aside competition. The company has been registered with the government since 2002 and maintains recurring delivery order relationships with the DLA spanning multiple single-award IDCs, indicating stable supply-chain positioning for military vehicle maintenance logistics. Subcontracting work with BAE Systems anchors exposure to production-phase defense programs but remains small relative to the DLA prime footprint.
