01-04 GM 6.6L LB7 Reman Fuel Injector Set - AP55127

Alliant Power's remanufactured injectors are built for engines that demand the most out of their fuel systems in the toughest of conditions. The AP55127 is a complete 8-injector set — the technician's choice for restoring peak performance to your Chevrolet Silverado or GMC Sierra with the 6.6L Duramax LB7 engine.

Each injector is assembled with only OE or OE equivalent components. The bodies are 100% reconditioned to reduce leakage and extend life and performance back to like new. Once assembled, each injector passes a rigorous end-of-line test to OE specs on OE equivalent test equipment — checking for external and internal leaks, up to 15 different pressures and pulse widths, as well as injection timing beginning and end.
