These LS9 specific supercharger covers are intended to reuse all factory components. Lids come anodized black, and you will reuse your factory seals for the lid. The inside of the lid has been contoured to provide smooth airflow transitions both out of the blower and into the supercharger mating surface.
We offer custom engraving for $85. Please note that we will NOT engrave copyrighted material! If you opt for custom engraving, please be sure to communicate with us at firstname.lastname@example.org. If you can provide a vector file of the engraving (either .eps or .ai), this is preferred, otherwise a VERY high resolution jpg/png file will work. The image must be strictly black and white.
