Ultra Black Gasket Maker to the Lingenfelter

supercharger assembly. The three pins sticking
out of the supercharger drive shaft in the front
cover go into the three holes in the plastic
coupler that are not occupied by the pins from
the supercharger assembly.

removed from the end of the shaft, tap the
end of the shaft with a rubber mallet to seat
the plastic shaft coupler. Check to make sure
the supercharger assembly turns smoothly. If
it doesn’t turn freely, tap the end of the shaft
again to fully seat the plastic coupler.

front cover/housing. Install the supplied dowel
sleeves into the LS9 supercharger housing.
Install the sleeves in the bottom left and bottom
right hand corner of the supercharger housing.
DO NOT install sleeves on the front cover.
NOTE: Some early engines may not have
dowel sleeves in the cover. Dowel sleeves
should be used on these early engines as well.
