The catalog for a heavy duty pickup splits in ways that are not obvious from the outside, which is why the model year matters. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.
The parts we ship most for the 2010 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.
Warranty is the quiet argument for factory parts. A genuine GM component carries GM's coverage, and on anything that touches the powertrain or the emissions system that coverage is worth more than the price difference on the invoice.
By 2010 the GMC Sierra 2500 HD was well into its production run, so most early build changes had been worked through. 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.
