Masso Diesel is a diesel injection specialist with more than 10 years rebuilding, testing and supplying diesel fuel system components. We run a full injection shop and parts counter in McAllen, Texas, backed by our operation in Mexico — so U.S. shops get bench-tested parts and border-quick turnaround from one source.

We are a member of the Association of Diesel Specialists (ADS), and we source through authorized distributor channels including Alliant Power, Dipaco, Denso, Garrett, OT Diesel and Cummins. Every unit is cleaned, tested and inspected before it ships, and every product carries a 12-month warranty against manufacturing defects.

We supply diesel injectors (Common Rail, HEUI, EUI, Piezo Electric and mechanical), remanufactured turbochargers and VGT actuators, injection and high-pressure pumps, injector and pump solenoid coils, and a full sensor line — camshaft and crankshaft position, engine and transmission speed, turbo speed, throttle and pedal position, EGR, knock, temperature and ABS wheel speed.

Our catalog covers on-highway trucks, construction and agricultural equipment, industrial engines and golf carts — Caterpillar, Cummins, Detroit Diesel, PACCAR, Navistar, John Deere, Case IH, New Holland, Ford, Volvo, Bendix and Haldex applications.
