JASPER WELLER, LLC

JASPER WELLER LLC specializes in the manufacturing of precision motor vehicle transmission and powertrain components, with demonstrated experience producing critical assemblies for specialized government vehicle fleets. Their core capability centers on the design, fabrication, and delivery of high-tolerance mechanical parts such as knuckle assemblies, engineered to meet the demanding operational requirements of heavy-duty utility and field service vehicles. The contractor’s technical expertise lies in precision machining, assembly integration, and compliance with vehicle-specific performance standards for mission-critical applications, particularly in rugged environments. Their specialization in powertrain subsystems suggests deep familiarity with driveline dynamics, load-bearing joint systems, and component durability under extreme conditions, positioning them as a niche supplier for agencies requiring robust, non-standard vehicle parts not available through commercial channels. The company has delivered products to the Department of Energy, specifically supporting the Western Area Power Administration’s Rocky Mountain Region fleet operations. This engagement indicates a focused relationship in supplying durable, mission-specific components for utility and maintenance vehicles used in remote or high-risk terrain, aligning with DOE’s infrastructure and energy delivery missions. JASPER WELLER LLC operates under NAICS 336350, which defines their primary market as the manufacturing of transmission and powertrain parts for motor vehicles. Their market positioning is highly specialized, serving government fleets that require custom or low-volume mechanical assemblies beyond standard OEM offerings, particularly in the utility and transportation support sectors. The entity is structured as ZZ, indicating a small business with no active federal certifications. Based in Grand Rapids, Michigan, the company leverages its Midwest manufacturing base to support federal procurement needs, maintaining a focused, agile presence in the defense and energy vehicle supply chain without broad certification-based market access.
