Quality Turbocharger Components LLC

Quality Turbocharger Components LLC, a Houston, Texas-based self-certified small disadvantaged business structured as a limited liability partnership, provides federally mandated safety inspections, repairs, troubleshooting, diagnostics, and preventive maintenance services for the U.S. Army's ultra-low emitting locomotive fleet as a prime contractor exclusively to the Department of Transportation's Immediate Office of the Secretary (100% of recent awards). The vendor competes on a full-and-open, non-set-aside basis despite its SDB certification, holding two active indefinite delivery contracts with the Department of Transportation and generating delivery orders across sixteen Army installations nationwide.

Quality Turbocharger Components LLC operates in concentrated, single-customer territory. All eighteen prime awards worth $283.6 million in combined potential value flow from the Department of Transportation's Immediate Office of the Secretary Transportation, with zero subcontractor engagement and no work through other federal agencies. This extreme concentration reflects a strategic partnership anchored to Army rail fleet operations at Fort Riley, Kansas; Fort Cavazos, Texas; Fort Lewis, Washington; Fort Campbell, Kentucky; Fort Sill, Oklahoma; Fort Carson, Colorado; Concord, California; Cambridge, Massachusetts; and subordinate installations.

The vendor holds two active IDCs: a single-award contract awarded August 8, 2023, with a $7.356 million ceiling through April 30, 2027, supporting Army ultra-low emitting locomotive technical support; and a larger multiple-award contract awarded September 25, 2026, with a $268 million ceiling through September 24, 2031, covering manufacture or refurbishment of road-switcher locomotives, freight cars, and railcar movers, as well as in-field sustainment including periodic safety inspections, preventive maintenance, and emergency repairs. Against the older single-award IDC, the vendor has issued approximately twelve delivery orders with aggregate value around $4.2 million and individual order values ranging from $12,159 to $1.493 million. Recent named delivery orders include a $1.467 million award for maintenance services at fourteen Army locations nationwide (May 19, 2026, completion September 30, 2026), a $1.494 million order for locomotive repairs and diagnostics across sixteen Army rail installations on 35 locomotives (December 10, 2025, completion June 30, 2026), and a $1.172 million award for safety inspections and technical support at Cambridge, Massachusetts (August 14, 2025, completion April 30, 2026). Against the newer multiple-award RMS contract, the vendor has received at least one delivery order — an $886,438 award for rail rolling stock modernization and sustainment technical field support at Fort Hood, Texas (September 29, 2026, completion March 29, 2027).

Activity has grown unevenly: four awards in 2023, six in 2024, three in 2025, and five in 2026 year-to-date. Within the next twenty-four months, only one award ($886 thousand) reaches ultimate completion, exposing the vendor to minimal recompete cliff; the older single-award IDC's April 2027 completion date falls outside the twenty-four-month window. Service Contract Inventory records show $509 thousand in invoiced revenue in FY2024 across 0.5 FTEs, with zero FY2025 SCI activity — a partial and minimal view of the vendor's federal service footprint, as SCI excludes goods, products, and most military contracting. Government-paid rates on SCI-reportable prime records ran $466.49 per hour. The vendor performs work exclusively in-house; across SCI-reportable prime contracts, the average subcontractor hours share was zero percent.

Scope encompasses federally mandated safety inspections, preventative maintenance, troubleshooting and diagnostics, brake and engine system repairs, air brake system maintenance, fuel injector replacements, electronic component troubleshooting, technical training, and emergency on-site support, with work performed across thirty-five to thirty-nine locomotives per delivery order. Primary NAICS coding runs to Support Activities for Rail Transportation (sixteen awards) and Railroad Rolling Stock Manufacturing (two awards); primary PSC is Maint/Repair/Rebuild of Equipment—Railway Equipment (thirteen awards).
