ATI ProCharger Hummer H2 Supercharger Kits

ProCharger Intercooled supercharger kits for 03-04 Hummer H2

With ProCharger technology, reliably adding big horsepower to your engine is a lot easier than you may think. Intercooler ProCharger systems utilize exclusive features and proven technology to deliver 55-75% gains on pump gas to your Hummer H2. ATI is the only company that has put stock 5.0's, LT1's, 4.6's and LS1's into the 11's, and routinely delivers 12-second ET's to completely stock TPI applications running pump gas. ATI is also the only company that guarantees the best performance gains. Nothing else even comes close! For modified street applications, ProCharger technology delivers 10-second ET's with the least amount of engine modifications - and with the supercharger still under warranty. These systems are 100% complete, and daily drivability is unchanged. Thanks to ProCharger's superior compressor efficiency and standard 2-row intercooler, these kits provide the coolest engine intake air temperatures ever. This exemplary durability led to the industry's best warranty coverage (the H2 kit has a standard 12-month warranty). The "other guys" don't warrant their kits for even 1 day.
