A supercharger is a belt-driven air pump bolted directly to the top of the engine that force-feeds it more air (and with a matching tune, more fuel) than it could pull in on its own - the single biggest power upgrade on this list, well beyond what a cat-back, intake, or header can do alone.

why this one — Magnuson is GM's own supercharger supplier for factory-supercharged GM vehicles, and this TVS2650 kit is engineered specifically for the L86 6.2L (not a shared 5.3L unit), confirmed compatible with both 2014-2018 Chevrolet Silverado and GMC Sierra 1500. A real, specific claimed number (640 hp/579 lb-ft at the crank) beats a vague "more power" pitch.

where the number comes from

Magnuson's own product page states "640 hp and 579 ft-lbs at the crank" and "+45% Horsepower" for this exact kit.

heads up

Major forced-induction upgrade - includes Magnuson's own PCM calibration; expect a supporting-mods conversation (fuel, plugs, cooling) and potential powertrain warranty impact.
