2020-2026 Chevy Silverado 2500HD Engine & Performance

Engine and performance upgrades fitted for the 2020-2026 Chevy Silverado 2500HD, including both the 6.6L L8T gas V8 and the L5P Duramax diesel. Stock includes cold air intakes from S&B and AFE, EGR delete kits, downpipes, tuners, catch cans, and CP3 conversion kits for L5P trucks.

Will a tuner or intake void my factory warranty? No, the Magnuson-Moss Warranty Act protects you -- GM must prove the modification caused the failure to deny a claim. Emissions-related parts are sold for off-road or competition use where applicable.

Every part listed here is verified to fit your Silverado 2500HD -- no guesswork.
