Sourcing parts for a heavy duty pickup comes down to matching the right generation, and that is where most orders go wrong. One-ton heavy duty truck in single and dual rear wheel and chassis cab form.
For 2014 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 2014 GMC Sierra 3500 HD are transfer case components, fifth wheel and gooseneck hardware, trailer brake controllers, mirror assemblies and tailgate hardware. 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.
Where geography matters is landed cost. A heavy part quoted a few dollars cheaper by an East Coast seller often costs more delivered to the middle of the country than the same part shipped out of Dallas. Compare the total, not the sticker.
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. Cross-shopping a related truck?
