2015-2019 GMC Sierra 3500HD Throttle Improvement

Every throttle controller here is fitment-verified for the 2014-2018 GMC Sierra 3500HD, both 6.0L gas and 6.6L Duramax. Plug-and-play modules from Banks Power (PedalMonster) and Edge Products (Amp'd 2.0) install behind the accelerator pedal in under five minutes -- no cutting, splicing, or ECM reflash.

Will a throttle controller add horsepower? No -- it sharpens pedal response by eliminating factory drive-by-wire delay, which feels dramatically quicker but does not change fuel, timing, or boost. Pair with a tuner for real power gains.

If it is listed here, it fits your 3500HD -- guaranteed.
