Auto parts for new and vintage vehicles in San Gabriel Valley


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.

Our team is made up of experts in truck parts and auto parts for new and vintage vehicles. We specialize in light, medium and heavy duty trucks as well as industrial equipment. The parts we work with include hitches, brakes, suspensions, exhaust, clutches, filters, pumps, belts, cargo control, hoses, hydraulics, lights, bearings, seals, u-joints, tools, and more. We work with major lines, such as Peterbilt, Freightliner, Western Star, Kenworth, Mack, International, Volvo, Ford, GMC, Chevrolet, Caterpillar, Cummins, Detroit, Mitsubishi, Isuzu, Hino, John Deere, Case, Bobcat, Perkins, Kubota, Deutz, Hatz and many others. If you are in need of transmission, steering, electrical, or other vehicle parts, please contact one of our sales associates right away.
