Area Diesel Service Inc.

Area Diesel Service Inc. is a veteran-owned small business headquartered in Carlinville, Illinois, that specializes in supplying critical diesel engine components and replacement parts to the United States Department of Defense. The company has established itself as a specialized supplier within the defense supply chain, focusing on providing high-quality diesel engine spare parts essential for maintaining and sustaining military ground vehicles, maritime vessels, aircraft, and support equipment across all service branches. Area Diesel Service Inc. has built a robust contract history with federal agencies, particularly the Defense Logistics Agency (DLA), which has become its primary customer. The company's expertise in manufacturing precision diesel engine components, combined with its veteran-owned small business status, positions it as a reliable partner for the federal government's logistics and maintenance operations.

Area Diesel Service Inc. has delivered an extensive array of diesel engine components through its federal contract awards, with the vast majority of work performed under firm fixed-price purchase orders and delivery orders issued by the Defense Logistics Agency Land and Maritime division. The company's product portfolio includes fuel metering pumps, fuel injector assemblies and nozzles, turbochargers and turbo superchargers, cooling system pumps, electrical starters and starter-generators, fuel cam actuators, plunger and bushing assemblies, and various related diesel engine components identified by National Stock Numbers. Many of these awards have carried total small business set-aside designations, leveraging the company's veteran-owned status, while others have been awarded without set-aside designations. Contract values have ranged from less than one hundred dollars for miscellaneous small components to over $196,000 for larger fuel injection parts kits and fuel injector nozzle orders. The awards span multiple fiscal years, with recent contracts awarded in September 2025 for fuel metering pumps valued at approximately $1,900 each, and historical contracts dating back to 2022. Beyond the DLA Land and Maritime division, Area Diesel Service Inc. has also received awards from DLA Aviation and DLA Construction and Equipment, demonstrating its broad applicability across multiple defense logistics operations. The company performs all work at its facility in Carlinville, Illinois, with delivery to DLA distribution depots located throughout the Continental United States and Overseas Continental United States locations.

Area Diesel Service Inc. currently holds multiple Indefinite Delivery Contracts with the Defense Logistics Agency Land and Maritime, establishing it as a preferred supplier for recurring diesel engine component requirements. The company maintains approximately 15 active IDVs with ceiling values of $250,000 each, covering various diesel engine component categories including fuel metering pumps, fuel injectors and injector assemblies, fuel injection nozzles, turbochargers and turbo superchargers, cooling system pumps, electrical starters, fuel cam actuators, and plunger and bushing assemblies. These IDVs are structured as single-award contracts designated as total small business set-asides, allowing the DLA to leverage Area Diesel Service Inc.'s veteran-owned small business status while establishing reliable sourcing mechanisms for high-demand spare parts. The contracts typically have one-year performance periods with estimated delivery order frequencies ranging from three to eleven orders annually and guaranteed minimum order quantities specified for each vehicle. Recent IDVs awarded include contracts effective through October 2026 for fuel metering pumps, August 2025 for various diesel engine components, and April 2026 for fuel injection nozzles. The IDVs enable the DLA to rapidly acquire critical low-dollar, high-demand spare parts without issuing individual competitive procurement actions for each requirement, streamlining the acquisition process while supporting military readiness. Under these IDV vehicles, the DLA has issued hundreds of delivery orders over the contract periods, with individual task order values ranging from zero dollars (administrative orders) to over $196,000, demonstrating the flexible procurement mechanism's effectiveness in supporting military logistics operations globally.
