Dynomite Diesel Fuel Injector Install Kit (Basic) for Chevy GMC (2001-2004) 6.6L Duramax LB7, Gaskets and Seals

This Dynomite Diesel Basic Fuel Injector Install Kit gathers the gaskets and seals required for an injector replacement on Chevy and GMC 2001-2004 6.6L Duramax LB7 trucks. It is the supporting hardware you need to reassemble the engine correctly after the injectors come out.

The kit includes two lower valve cover gaskets, two LB7 injector return line seal kits, two LB7 injector seal kits, an LB7 injector cup O-ring kit, FICM fuel line banjo seals, RTV sealant, upper radiator pipe and heater pipe seals, and two red threadlockers. Together these cover the fresh seals that should be replaced any time the LB7 injectors are serviced.

It is aimed at owners and shops replacing LB7 injectors, a job known for injectors buried under the valve covers. Having the right gaskets and seals on hand keeps the repair moving and helps avoid leaks after everything goes back together.

This is a parts kit, not an injector set, so injectors are purchased separately. The kit carries a 3 Year warranty. Given the depth of the LB7 injector job, professional installation is recommended so the seals are set correctly the first time.
