Mac Motors, Inc.

Mac Motors, Inc., a small business Subchapter S corporation based in Warminster, Pennsylvania, supplies HMMWV parts, automotive components, and specialized insulation materials to federal agencies as a prime contractor under Total Small Business set-asides and full-and-open competitions. The vendor operates almost exclusively as a prime (100% of recent awards), with one sub-award under Sierra Nevada Company for C-UAS FSR support automotive parts as of December 2025.

Mac Motors' capability portfolio centers on HMMWV maintenance, repair, and replacement parts — engine components, suspension systems, electrical parts, brake assemblies, filters, hoses, control arms, differentials, transfer cases, and specialized fasteners — supplied primarily to the Department of Justice Bureau of Prisons and the Department of the Army. The vendor holds a five-year single-award Indefinite Delivery Contract with the Bureau of Prisons Central Office valued at $211,272.42 running through August 2026, which anchors most of its recent activity. Representative recent awards include a $69,575 Total Small Business purchase order with the Bureau of Prisons for 23 line items of HMMWV maintenance components (May 2026); an $18,466 Total Small Business purchase order with Federal Correctional Institution Gilmer for HMMWV up-armor components (November 2025); and a $23,532 Total Small Business purchase order with the Bureau of Prisons for Humvee windshield kits (July 2024). The vendor also supplies insulation fillings and sleeving materials to the GSA Federal Acquisition Service under full-and-open competition, with individual purchase orders typically under one hundred dollars.

Customer concentration skews heavily toward correctional and Army logistics. The top five customer categories account for 76% of awards by count and 77% by potential value. The Department of the Army Materiel Command's TACOM Life Cycle Management Command (567 awards, $121 thousand combined potential value) and the broader Department of the Army (428 awards, $229 thousand) lead by volume, but the Department of Justice Bureau of Prisons Federal Correctional Complex Victorville (99 awards, $1.4 million) and the GSA Federal Acquisition Service (48 awards, $2.6 million) anchor most of the dollar value. The Bureau of Prisons Central Office and individual correctional institutions collectively represent the highest-value customer base.

Mac Motors places work under two GSA Blanket Purchase Agreements — GS06F4MCMA (504 task orders) and GS07FBMACM (135 task orders) — and holds positions on Army Indefinite Delivery Contracts W56HZV05AJ033 (33 task orders, $81 thousand combined potential value) and W56HZV09AJ020 (19 task orders, $701 thousand combined potential value). Recent activity has declined year over year — ten awards in 2022 to one in 2026 through May — reflecting both the portfolio's shift toward calls against standing IDCs and BPAs rather than new contract awards, and lower volume of new solicitations. The vendor's combined potential value across all awards stands at $7.5 million, with $7.1 million obligated. The primary NAICS concentration is Hand and Edge Tool Manufacturing (1,277 awards), though this classification reflects the granular nature of purchase-order-level parts procurement rather than the vendor's dominant operational footprint, which is HMMWV and automotive parts supply to correctional and Army customers under Total Small Business set-asides.

Mac Motors distributed parts for AM General since 1980 and has been serving all branches of the U. S. Military ever since. Emerging from a small parts room then to a large warehouse distributor today, Mac Motors has strived to make the interests of their customers their own.

Customer service has always been important to Mac Motors, and in 2007 a parts warehouse in Fort Polk, LA was purchased in order to better service customers by being able to ship out of multiple locations.This cuts down on the shipping cost to the customers.

For over 40 years Mac Motors serviced the United States Postal Service and in 2008 sold that division to Jasper Engines.
