S&S Diesel Motorsport stock replacement injectors are a high-quality solution for 2001–2004 Duramax LB7 engines. Designed to deliver factory fuel flow with improved durability, these injectors are ideal for customers who want OEM-level performance without increased fueling.

New SAC00 Injector Design

S&S Diesel Motorsport SAC00 injectors are a major upgrade for LB7 Duramax owners seeking long-term reliability. S&S partnered directly with Bosch to develop a stock-flow SAC-style nozzle to replace the failure-prone factory VCO nozzle, which is no longer produced.

The result is an emissions-friendly, direct-replacement injector that maintains stock fueling while dramatically improving injector lifespan.
