60 HP:

Our most popular LB7 performance injector. These injectors are a 'mild performance' upgrade - great for a daily driver or for towing purposes. The 60HP injector is very popular because no other modifications are required - install and drive! Customers love the extra 'pep' and the majority report a slight gain in economy (when they are not having fun with the extra power!)

These injectors feature a SAC style nozzle which is an improvement over the factory VCO style nozzle and is more resistant to the excess heat generated in performance applications. One of the inherent weaknesses of the factory LB7 injector design was the VCO nozzle which was prone to premature leakage causing smoke problems at idle. SAC nozzles are much more robust and not prone to this type of failure. It is our opinion that upgrading to SAC type nozzles is one of the best investments an LB7 owner can make.

Nozzle flow is up to 45% over stock - the industry considers this a 60HP nozzle. Results can vary depending on tune and condition, and other modifications. Your power (and mileage) may vary up or down!


We also offer 65% over and 100% over injectors for serious performance builds. Custom sizes are available also. High flow injectors may require additional fuel system modifications, such as increased lift pump capacity, and stroker or dual CP3 pumps. Please do your research carefully before purchasing extreme high-flow injectors.

We also offer lower valve cover gasket kits, glow plugs and injector installation kits - see related items below.

(Please note that later 2004 Duramax engines use the LLY engine and a different injector. To identify your engine, check the eight digit of the VIN - if you have an LB7 engine, it will be a '1')
