Chevy Duramax 08-10 LMM Brand New 300 Percent Over Injector Set (SAC Nozzles) Dynomite Diesel

The Dynomite Diesel DDPNLMM-600 is a brand new 300% over injector set for the 2008-2010 Chevy Silverado and GMC Sierra 2500 HD and 3500 HD trucks with the 6.6L LMM Duramax. This is a large, high-flow injector aimed at serious builds.

Built from brand new OE injectors, the set carries no core charge and nothing to send back. Each injector is sized 300% over stock with a modified body and a 6-hole SAC nozzle sprayed at 159 degrees, and the set ships balanced and matched as a group of 8 for consistent fueling under heavy demand.

A 300% over set is built for sled pullers, race trucks, and high-horsepower LMM builds where fuel volume is the priority. This is not a mild street injector; it is meant for owners who have committed to a big-power combination.

Running this size safely requires aggressive tuning, a high-output supporting fuel system, and turbo work sized to the fuel. Dynomite Diesel backs the set with a 1 year unlimited mile warranty. Confirm this injector size suits your build with your tuner first, as injectors are not returnable once installed.

For a dedicated high-horsepower LMM build, this brand new 300% over matched set supplies the fuel needed at the top of the range.
