The shop that installed the kit (a very reputable one) had a really tough time even getting them to go in. The blocks themselves are fine, but the stock rear springs on a 3500 are bone-jarringly stiff to begin with, as I'm sure you're aware.
That is what I was thinking too, that is why I was curious about alternative spindles. I think weld tec makes a great product but for my use his stuff is way way overkill for me. As far as spindles go anyway, to me a lift spacer is a lift spacer no matter whos name is on the box. I can't seen one aluminum spacer being far superior to another if they are both made of the same grade material.
