Lift kit spacers???

From my experience, I had a spacer kit amd noticed that the ride was a little bit harder than original, so I saved money and got all 4 5100's and also got All pro upper controls, since i wanted to have the same height that i had with the spacers I installed the 5100's on the highest position and now that I drove the truck a least 200 miles on the street and on the freeway. The truck looks great but rides like a rock. Im thinking on setting the Blinsteins at 0 and install the spacer again. Watched the blinstein video several times and I can't seem to understand the difference on lenght. They show 3 diferent kits and the diferent heights, but if you set the blinstein 5100 at 2.5 it is the same overall lengh as the original shock with the 2.25 spacer.

Please note that I don't go off road, just some shitty streets and go over some rail tracks.

 

What brand/manufacturer was the kit?

 

I don't even have a brand name....It was one of those $100 Ebay kits. Blocks and top plate spacers are so "generic" by design, they don't really need to be "brand name".
