Torquemaster injectors incorporate proprietary modifications that slightly increase torque output only under full-load conditions. At any condition less than full load the output remains at stock levels to maintain stock driving characteristics, economy, and emissions. Torquemaster injectors are a perfect "drop-in" with no other modifications required.

50 HP :

Our most popular injector. These injectors are a 'mild performance' upgrade - great for a daily driver or for towing purposes. The 50HP injector is very popular because no other modifications are required - install and drive!

Nozzle flow is 30% over stock - the industry considers this a 50HP nozzle and this has proven realistic in real world experience. Results can vary depending on tune and condition, and other modifications. Your power (and mileage) may vary up or down!

100 HP:

For the more serious performance enthusiast, these LMM injectors for sale flow 45% over stock.


We also offer injectors sizes from 60% over all the way to 500% over for the most serious and truly insane performance builds! (Select from available options below.) Custom sizes may be 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.

Please note that Duramax LMM performance injectors will ship to EXACT match credit card address or PayPal address only. Non-compliant orders WILL be cancelled.
