    Resolve white idle haze, excessive return rates, and fuel-diluted engine oil with our selection of 2001–2004 Chevy Silverado and GMC Sierra 2500HD/3500HD LB7 Duramax fuel injectors. Because the 6.6L LB7 common-rail injectors are mounted under the valve covers, installing reliable, high-durability components is essential to avoid repetitive labor. We supply brand-new genuine Bosch OEM units featuring updated chrome ball seats, modern S&S SAC nozzle sets engineered to outlast obsolete VCO designs, and high-flow performance injectors for modified builds. Browse our complete line of stock-flow and upgraded LB7 injectors below to restore clean combustion and dependable power.
