Collection: 2015-2019 GMC Sierra 2500HD Throttle Improvement

Every throttle controller here is fitment-verified for the 2014-2018 GMC Sierra 2500HD. Covers 6.6L Duramax LML/L5P and 6.0L Vortec gas trucks, with units from Banks Pedal Monster, aFe Sprint Booster, and Bully Dog across Regular, Double, and Crew Cab SLE, SLT, and Denali trims.

Does a throttle booster add horsepower? No -- it eliminates factory drive-by-wire pedal lag so existing power arrives the instant you press the throttle, with reverse-safe and valet modes for towing.

If it is listed here, it fits your Sierra 2500HD -- guaranteed.
