This is a Sources Sought Notice for an automotive axle assembly (NSN 2520-01-572-2738) used on HEMTT A4 vehicles, with a minimum quantity of 14 and a maximum of up to 28 units. The government does not own the technical data package, so potential suppliers must undergo qualification testing and evaluation to become an approved source. Becoming an approved source does not guarantee business but allows the opportunity to compete on future solicitations. No submission timelines, budget amounts, or performance location are specified in this notice. Interested parties should review the Source Approval Program and Source Approval Request package requirements via the provided TACOM website.
