2015-2019 GMC Sierra 2500 Accessories, Parts & Mods

Now based on the K2XX platform, 2015-2019 Sierra 2500 trucks command attention with their reinvigorating design. At the forefront is an impossible to miss fascia with a massive grille insert, flanked by projector beam headlights. Underneath the hood, the 6.6L V8 Duramax diesel or 6.0L Vortec V8 continue to power. The latter, however, is also offered in a natural gas variant. The gas Vortec retains its 360 horsepower/380 lb-ft torque ratings all the way through the generation, however the Duramax does see a substantial increase up to 445 horsepower/910 lb-ft by 2017 (LP5 designator). Improvements made to the independent front suspension and rear system help the truck ride better both unloaded and loaded than ever before. In addition to the structural upgrades, GMC focused a lot on the interior, blending aesthetics, comfort and practicality. In particular, this iteration of Sierra 2500 trucks saw a lot of tech thrown at them. 4G connectivity, MyLINK, Forward Collision Warning System and Lane Departure Warning, Front and Rear Park Assist, Hill Descent Control, Trailer Sway Control, Hill Start Assist were all available as early as 2015. With all these features, 2015-2019 Sierra 2500 pickups are still highly modifiable. Whether you need a larger transmission cooler for towing, new mags to showcase around the town or a full-time locking differential to pull yourself out of the mud, AmericanTrucks offers a large selection of aftermarket performance parts to equip your truck as needed.
