Cummins 5.9 COMP Hybrid Injectors


The first 5.9 Cummins, hybrid, Common Rail injector. They feature a thicker and stronger body to resist cracking.  Comp Hybrid injectors are made from hot rolled, heat treated and tempered steel.  No more worries of external cracks that fill the crankcase with diesel fuel. Comp Hybrid bodies are able to withstand extended high pressure use past 1800 bar. We are so confident in their strength we back the injector with a five year warranty replacement program.  Its simple; if one fails, we replace it. 

Comp Hybrids are meant for any 5.9 application and can be configured for mild towing to extreme high performance with multiple nozzle sizes and tuning levels available. Coupled to our APEX nozzles, the Comp Hybrid can produce over 2500hp without failures. Expect them to be available in the fall of 2019.


Comp Hybrids will require special installation parts and pieces that are included. These are 100% new and do not require a core charge. 

Pricing will be available in the fall of 2019
