The ProMAXX DEF Doser Decomposition Reactor Repair ProKit allows diesel technicians to quickly complete an on-the-truck repair on Cummins ISX, ISB, ISC, ISL, Navistar N9, N10, N13, and PACCAR MX-11/M-13 engines. The kit’s ProPlate fits over the dosing valve mounting plate correctly aligning to its bolt holes. The included machine-shop-grade drill bit and tap tooling removes broken bolts and chases the threads, restoring them to factory new. The kit is ideal for diesel repair shops that work on vehicles such as Cummins-powered tractors, buses, fire trucks, excavators, garbage trucks and even the light duty Dodge Ram 6.7L pickup truck engine.
