Starting with the highest quality 8620 steel, gears are precision hobbed to AGMA Class B Tolerances to produce a true involute tooth form for a high contact ratio. Then a fully controlled heat treatment process is applied. Available in 29 gear ratios. All gear sets are matched sets and are NOT to mixed with other sets, even with the same tooth count.
NOTE: In Supercharger applications, the larger gear goes on the input shaft from the engine and the smaller gear goes on the output shaft to the supercharger.

The Supercharger Store Gear sets which are specifically designed for use with centrifugal Superchargers weight half the amount of the gears used by all other Centrifucal Supercharger Gear Drives avaliable. Our gear drive may only weigh 2 lbs less that the competition the real advatange is they have well less than half of the rotating mass. Less rotating mass means less loads on the system and faster reaction to engine speed changes.

About The Supercharger Store

The Supercharger Store is the original innovator of the crank driven centrifugal supercharger gear drive and is celebrating more than 17 years as the source for centrifugal superchargers. We specialize in centrifugal superchargers and only centrifugal superchargers. With kits from the best brands in the industry, our specialty kit using the best head units available and crank driven setups, we are the best source for centrifugal superchargers. Our gear drives are designed, manufactured, and built in the US and have propelled centrifugal superchargers to the top of the drag racing scene. Specifying a centrifugal Supercharger setup for a custom build motor is not something left to the catalog specialist. Calculations on the performance and sizing need to be run and not many sellers have the background to do this. We do and we do it every day.
