Alliant Power DTech DT660024 is a new injector installation kit, also called an injector mounting kit, for the GM 6.6L Duramax LLY, LBZ and LMM. The maker lists it for 2004.5 to 2010 Chevrolet and GMC pickups with the LLY, LBZ or LMM, and for Chevrolet Express and GMC Savana vans and Chevrolet Kodiak and GMC TopKick C4500 and C5500 trucks with the LLY or LMM. Alliant also lists Workhorse Custom Chassis.

Each kit has one injector body o-ring and one nozzle washer for one injector, so a full set of eight injectors takes eight kits. The 2001 to 2004 LB7 takes a different kit, DT660019.
