I was wanting to lift my truck in the front just to level it out about 2" or around there. I looked at several spacers and they all said the same thing *not for extended cabs* having called chevy and verified there is zero difference between a single cab and extended cab 1500 I just ordered them. Well I put them on and I only got about an inch not a huge deal as I didnt believe id honestly get 2.5". But here is the huge part the coil does not seat properly into the spacer which is very dangerous! They are also made from some cheap cast metal.

Now I have to take them back out and give another set a shot to see if they actually work. Will post pics later.
