04.5-05 LLY Duramax 50 hp Stage 1 Injector Nozzles





04.5-05 LLY  Duramax 50 Horsepower Nozzles  


Make your Duramax Fly. With the Allison 5 and 6 speed, the Duramax is already fun to drive. Why not add an addition kick with DDP Injectors. Unlike an electronic box, honed performance injectors are almost impossible for a factory technician to detect. With DDP's Balance Honed injectors you can be confident that your warranty will not be compromised and you'll have the extra pulling power to beat your friends up the mountain.

These 50 horsepower nozzles will give you 50hp at the wheels.  You can use these in conjunction with an aftermarket electronic box or downloader without the worry of draining the fuel rail dry.  These injectors work equally well in a completly stock truck.

Mileage will increase about 1-2 miles per gallon once the initial fun wears off and you start driving normally again.


As always, this product is covered by our 3 year unlimited mileage warranty and our 30 day money back guarantee.  Please see our Policies section to read more.
