Who We Are:

Weller Truck Parts began its history in Muskegon, Michigan in 1928 when Harry Weller, a small body shop owner, found value in recycled parts for the auto industry. The small business thrived so much that in 1949, Harry moved Weller Truck Parts to nearby Grand Rapids, MI. Since that time, Weller Truck Parts has continued to grow under the direction of the Weller family.

In 2014, Weller became a member of the Jasper Holding family of companies and a 100% Associate Owned ESOP. Today, Weller continues to grow and out-service the competition by providing an engineered solution for efficient and cost-effective repair, removing the otherwise defunct units and parts from the path to a landfill.
