Fits 2001-2004 Duramax LB7 only.

Kit contains all of the common gaskets and oring seals normally replaced in a head gasket job. We have never replaced the lower rubber valve cover gaskets unless destroyed so we have omitted them from this kit. Kit includes 2 grade C head gaskets, exhaust manifold and up pipe gaskets, injector install coppers, orings, and return seals, themostat housing gaskets as well as orings for heater, hot pipe, and bypass tube, EGR gaskets, intake flat rings and orings along with a tube of AC Delco sealant for the intake manifold to head.

"We do not use the latest GM/LML style head gaskets in our kits. I believe that the LML style gasket is a cost cutting measure and that the riveted version of the original style gasket was and still is the best so this is what we provide." -JK

The HB kit is designed to get the maximum voltage possible to the headlamps while relieving the strain on the headlight switch, and undersized factory wiring. The result is much whiter brighter lights increasing visibility by putting more light on the road in front of you. There are currently two kits available. The first fits most any vehicle using 9005 and 9006 lamps. This includes most GM 4 lamp composites from 1990 on. For GMC Denali style lights with all 4 9005 lamps, you'll need to note so we can build special.

All kits sent will be for 9005 and 9006 headlamp setups unless otherwise noted.

Set of 8 brand new OEM lines. Replace all 8 when doing your injectors. Yes they are expensive, but note that pile of rusty crap that you found in the injector inlet came from these lines. Rust and debris will build up between the line nut and the line even in the gentlest of climates. When the nut is turned will grind up this debris which will run down into the injector inlet bowl. Cleaning is impossible to do properly and any media blasting will leave embedded debris that will dislodge over time. New lines are plated to resist this rusting, but a good preventative after installation will help protect even further.
