GMC Sierra 1500 or Chevy Silverado 1500?

The GMC Sierra 1500 and the Chevy Silverado 1500 are closely related trucks, and many parts are sold for both, so each one gets its own page here. Of the 5 headers on this page, 4 are also listed for the Chevy Silverado 1500 and 1 is listed for the GMC Sierra 1500 only. The Chevy Silverado 1500 page lists 8 that are not on this one. Check the fitment notes on each part before you order, because engine and trim still matter.
