LMM Duramax Injector Set - Remanufactured Direct-Fit Diesel Replacement

Overview

This is an direct-fit injector set for the LMM Duramax diesel. It is professionally remanufactured to OEM specification for a professional-grade repair that restores proper function and reliability to your truck.

What It Does & How It Helps

The injectors atomize and meter fuel into each cylinder. Worn injectors cause a knock or rattle, smoke, rough idle, fuel in the oil, and misfires. A matched set of quality remanufactured injectors restores clean fuel delivery, smooth idle, and full power.

Fitment
