For years one of the most aggravating chores of engine assembly has been the difficulty of obtaining bracketry and accessories to final dress an engine. Until now the industry has offered only crude OEM stamped steel bracketry with limited adjustability requiring modifications to make them fit in nearly all applications. These problems brought to our attention the need to design bracketry to mount engine accessories that are not only attractive but strong with a quality fit every time. We have compiled our most popular components into kits. Both naturally aspirated and supercharged versions are available. Our "Standard" version combines quality and cost efficiency while our "Deluxe" versions represent the very best in available bracketry and accessories available today. Each kit includes all necessary hardware.

Note: Supercharged version does NOT include a supercharger pulley as it is included with the purchase of your supercharger.

We make it easy to install you supercharger on a dry sump engine!  this kit includes everything you need to make it work.  The dry sump adapter bracket lowers the pump enough to mount the alternator to the Keith Eickert Water Crossover which is also used for mounting the power steering pump driven off a Hardin Dual or Triple Stage Raw Water Pump.
