DDP DDPNLB7-SM DURAMAX 01-04 LB7 CUSTOM SUPER MENTAL BRAND NEW INJECTOR SET

The DDPNLB7-SM injector set is Dynamite Diesel Performance’s entry-level matched injector upgrade for the LB7 Duramax. These injectors are flow-matched within a tighter tolerance range than typical OEM replacements, delivering enhanced drivability, smoother idle, and cleaner emissions – especially when used with mild tuning or stock calibrations.

This “SM – Small Match” set is ideal for daily drivers, tow rigs, and trucks with light mods who want improved injector quality without pushing excessive fuel. Built from brand-new Bosch OE injectors, they are not remanufactured and come pre-tested and balanced for plug-and-play installation.
