2007-2014 GMC Sierra 2500HD Engine & Performance

Engine and performance parts guaranteed to fit your 2007-2014 GMC Sierra 2500HD, including both the 6.0L Vortec gas and 6.6L Duramax LMM and LML diesel powerplants. Shop cold air intakes from S&B and AFE, EGR delete pipes, DPF-back exhaust systems, and tuners built for the LMM/LML platform.

Will a tuner or intake void my powertrain warranty? No, the Magnuson-Moss Warranty Act protects you, but any failure the dealer links directly to the modification can be denied, so keep a stock tune available for service visits.

Verified fitment on every listing, no guesswork at checkout.
