    High-Peak Horsepower. 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 W140AX 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. Kit includes everything you need to install the Whipple W140AX Supercharger. Be sure to read all instructions and verify all parts are present prior to beginning the installation process. If additional tools are required for installation, it's strongly recommended to ensure they're available prior to disassembly. Time to install is an estimate. Allow more than one day if you've never performed this type of install before.

    Application. The Whipple W140AX 2.3L Supercharger Kit fits 2007-2013 GMC Sierra trucks with a 4.8L engine.
