Dorman 955-1448 Passenger Side Mirror vs Action Crash GM1321332 Side Mirror

These are two different mirrors, not two versions of the same one. The Dorman 955-1448 is a complete power mirror assembly with a flat lens and black plastic housing, sized for the passenger side of a Silverado 1500. The Action Crash GM1321332 is a manual folding door mirror with a black textured finish, listed for 2009-2013 Silverado 1500. Buyers of the Action Crash part report it matches the factory part and installs easily, though some say it ships slowly and arrives without instructions. Match the mirror to your truck's original equipment first: if your truck has power glass, the manual Action Crash unit is the wrong part, and if it has manual folding glass, the Dorman power unit is the wrong part.

• Choose the Dorman 955-1448 if your Silverado 1500 came with a power passenger mirror and you want a complete assembly rather than a repair kit.
• Choose the Action Crash GM1321332 if your 2009-2013 Silverado 1500 has a manual folding passenger mirror and you want a direct factory-style replacement.
