    High Peak Horsepower Level. Only screw compressor style superchargers like the W140AX can provide a high peak horsepower level with a broad power band ensuring you feel a noticeable difference in horsepower when you upgrade from your OEM supercharger. The Whipple W140AX 2.3L Intercooled Supercharger Kit is both durable and dependable at low boost and high boost levels.

    Positive Displacement Design. This unique design approach provides maximum low-end torque in addition to high efficiency to optimize your top-end horsepower as well. Unlike the W140AX, centrifugal and turbo superchargers have significant lag time during shift points, on-off throttle, and whenever boosting is performed off the line.

    Installation. Be sure to verify fitment and your parts list prior to beginning the installation. Read all instructions and have all needed tools available. This kit includes an oversized intercooled air-bypass system, high flow air filter, high flow fuel injectors, 3 minute pulleys and everything you need to install this Whipple Twin Screw Supercharger in your 6.2L GMC Sierra.

    Application. This Black Whipple W140AX 2.3L Intercooled Supercharger Kit is designed to fit 2009-2013 6.2L GMC Sierra.
