DDP LBZ GM Injector 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 100 horsepower nozzles will give you 100hp 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. Enough fuel for 600+ RWHP. Biggest injectors sold without race waiver.

As always, this product is covered by our 1 year warranty.
