No, the ones I used were about 10 bucks each and I got them at
Parts Express. This is a great place to get surplus electronics, especially speakers and speaker box building supplies. I've been buying stuff from them for 4 years. In the "Keyword Search" box enter
actuator and the 3 or 4 motors they have will come up. Mine worked until the bolt that I used to hold the motors to the doors looseened up and then fell out

You just have to get all the slack out because they don't have much extra travel. I don't really think they're the best bet for trucks but they did work for awhile...some day I'd like to fix mine, but I dont' use the locks anyway so i'm not in a hurry.
It's a
multi-purpose passenger vehicle and it eats
SUVs for breakfast...get it straight!
