Select The Trim & Engine Of Your Vehicle Below
Sourcing parts for a heavy duty pickup comes down to matching the right generation, and that is where most orders go wrong. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.
Fitment questions account for roughly a quarter of the OEM orders we handle, and almost all of them trace back to the same cause: one vehicle, several nearly identical parts, one correct answer. The VIN resolves it every time.
For 2013 the underlying design was carried over, so the parts that split are the ones tied to options, trim and build date rather than platform. Heavy duty trucks split on cab and chassis configuration, single versus dual rear wheels, and gas versus diesel, and the catalog will often show several options for the same nominal part.
The parts we ship most for the 2013 GMC Sierra 2500 HD are mirror assemblies, tailgate hardware, EGR coolers, front hub assemblies and leaf springs and shackles. Every part listed here is a genuine GM component with the factory part number, not an aftermarket reproduction. On a heavy duty pickup these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.
Send us your VIN before you order and our parts specialists will confirm the exact part number for your vehicle. Orders placed by 3pm Central usually ship the same business day from our Dallas warehouse, which keeps transit times short across most of the country. Parts for the 2012 Sierra 2500 HD and the 2014 Sierra 2500 HD are listed separately, because the differences between adjacent years are real.
