Southwest Radiator Shop, Inc.

Southwest Radiator Shop, Inc., a family-owned manufacturer based in Little Rock, Arkansas, supplies engine cooling systems and related components to the Department of Defense as a prime contractor on full-and-open purchase orders. The company holds no SBA set-aside designations and competes entirely in unrestricted contracting. Since establishing federal contractor status in 2001, Southwest Radiator has maintained ISO 9001:2008 certification and demonstrates sustained competency in meeting Defense Department specifications for heavy-duty, industrial, and military applications.

Southwest Radiator's federal footprint is heavily concentrated with the Defense Logistics Agency Land and Maritime division, which accounts for 406 of the vendor's 457 total prime awards and $23 million of the $38 million combined potential value across all federal work. This represents 96% of recent award count and 61% of total potential value. The vendor's customer base spans ten distinct federal agencies, but the remaining concentration is marginal: the Department of the Army Materiel Command Contracting Command Detroit Arsenal holds eight awards valued at $1 million combined, with Defense Logistics Agency Aviation, the broader Defense Logistics Agency, and the Army Communications Electronics Command accounting for minimal volume. The portfolio reflects a highly specialized supply relationship: 262 of the vendor's awards fall under PSC Engine Cooling System Components (Nonaircraft), with secondary categories including hose and flexible tubing (79 awards) and miscellaneous engine accessories (47 awards). The NAICS profile tracks this specialization: air-conditioning and warm air heating equipment manufacturing dominates at 185 awards, followed by miscellaneous fabricated metal products and motor vehicle parts.

Recent award activity shows episodic purchasing rather than sustained volume growth. The vendor received two purchase orders in 2025 and two in 2026 year-to-date, down from historical patterns documented in the portfolio span. Three named recent purchase orders exemplify the work: a $25,914 firm fixed-price order awarded January 16, 2026, for engine coolant radiators with completion scheduled June 25, 2026; a $34,875 order awarded September 19, 2025, for protective dust caps, completing May 20, 2026; and a $13,135 order from Defense Logistics Agency Aviation awarded November 8, 2023, for radiator delivery, completed April 16, 2024. All work is performed at the Little Rock facility. The vendor holds no IDV or GWAC positions; work flows through DLA's indefinite delivery contracts including SPE7LX14D0056 (18 task orders, $435 thousand), SPM7LX13D0035 (15 task orders, $15 thousand), and SPM7L408D5M73 (10 task orders, $100 thousand). Combined dollars obligated across the portfolio are $11.7 million (31% of combined potential value), indicating significant awarded backlog relative to invoiced revenue. Southwest Radiator operates as a sole 100% prime contractor with no subcontracting footprint in the source data.
