Headlight Booster Harness
This is the harness only and does not contain bulbs
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.

High psi lines for Dmax LB7 set of 8ea
Special Order Item
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.
