Collection: 2007-2014 GMC Sierra 3500HD Throttle Improvement

Throttle response controllers fit the 2007-2014 GMC Sierra 3500HD, including WT, SLE, SLT, and Denali trims with the 6.0L Vortec gas and 6.6L Duramax diesel. Shop plug-and-play modules from Pedal Commander and BD Diesel that eliminate factory throttle lag on both drive-by-wire gas and diesel setups.

Will a throttle controller void my powertrain warranty? No. These devices plug into the accelerator pedal harness, store no data in the ECU, and unplug in seconds before a dealer visit, leaving zero trace.

Verified fitment on every listing, no guesswork at checkout.
