Collection: 2020-2026 Chevy Silverado 3500HD Throttle Improvement

Throttle response controllers fit 2020-2026 Chevy Silverado 3500HD, both gas 6.6L and Duramax 6.6L diesel trucks. Stocked options include Pedal Commander and aFe Power SCORCHER GT, with multiple drive modes and anti-theft lockout via the included app or in-cab controller.

Will a throttle controller void my factory powertrain warranty? No -- these devices plug into the accelerator pedal harness and add no permanent modifications, so unplugging restores factory throttle mapping before any dealer visit.

Verified fitment on every listing, no guesswork at checkout.
