Triangle Truck Parts proudly serves customers in Azusa, Covina, Baldwin Park and all over the San Gabriel Valley. In 1969 Don Scott purchased TTP and transformed it into a highly successful heavy duty truck parts retailer. After 50 years of ownership, the company remains in the hands of the Scott family. While still meeting the needs of the rock and sand industry we have expanded our coverage of lines over the years. We now cover light automotive parts all the way up to heavy industrial equipment.
