The 2020+ Silverado and Sierra 2500/3500 HD are heavy haulers — independent front, leaf-sprung rear, and available Duramax diesel. AT4 trims come with a factory off-road setup.
Fitment
Diesel (6.6L Duramax) trucks carry a heavy nose, so leveling and lift kits are spec'd for the added front weight. Single-rear-wheel vs dually 3500s change fender, wheel, and spacing parts. AT4 trims already sit taller, so parts differ from base trucks.
Before you buy
A leveling kit evens the rake and clears 35s on most; lift kits are available for more. Duallies and heavy towing change the parts list, so tell us how you run it. Alignment after any change.
Every part on this page fits the 2020+ Chevy Silverado & GMC Sierra 2500/3500 HD. Lift installs, leveling, and alignments available in Mesa, AZ — call 480-269-2833.
