how much to get GM to install a posi in 2004 silverado?? anybody know prices or anything... how long for install?.... or should i just quit being lazy take my *** to the dealer?

 

Are you looking for some kinda warranty thing? I'm assuming this is an aftermarket posi unit?!? I would go to a dedicated differential shop. It will definatley be cheaper. Without a gear swap, the posi swap labor should run around $250.

 

i think they will rape ya. i thought about doing the same thing, taking my eaton somewhere to have it installed. i did some research and attempted it on my own. glad i did. it wasn't that bad. i would do it again. the best way to learn is trial and error. you do it once, you gain confidence and are able to do it again and again. plus you get satisfaction doing it yourself and you save $$$.
