GRAND SLAM DIESEL SERVICES LLC

GRAND SLAM DIESEL SERVICES LLC specializes in the repair, rebuilding, and maintenance of heavy-duty marine and industrial propulsion systems, with deep expertise in diesel engine overhauls, turbocharger inspections and rebuilds, cylinder kit replacements, and gear case repairs for government vessels and equipment. Their technical capabilities center on high-output marine diesel engines—including the 6V92 model—along with associated components such as blowers, fuel systems, and auxiliary machinery, ensuring operational readiness for mission-critical maritime assets. The contractor demonstrates precision in diagnostic evaluation, component-level restoration, and compliance-driven repair documentation, distinguishing itself through hands-on proficiency in complex naval propulsion systems and rapid turnaround for time-sensitive field repairs. The company maintains a strong, consistent relationship with the Department of Homeland Security, delivering essential maintenance services for small boat fleets and maritime patrol vessels, including engine rebuilds, turbo inspections, and system diagnostics under operational constraints. They also support the Department of Defense with industrial diesel engine refurbishment and mechanical assembly assistance, indicating adaptability across military and coast guard operational environments. Their primary industry focus lies in shipbuilding and repair (NAICS 336611), where they serve as a niche provider of mechanical propulsion system sustainment, complemented by commercial and industrial machinery maintenance (NAICS 811310). This positions them as a specialized contractor for government agencies requiring skilled labor to maintain non-electronic, high-torque mechanical systems in harsh marine environments. As a small business based in Virginia Beach, VA, GRAND SLAM DIESEL SERVICES LLC operates with a lean, technically focused structure and holds no federal certifications. Their geographic proximity to major maritime operations enhances responsiveness to federal fleet maintenance needs across the Atlantic seaboard.
