Coil spring spacers... Good or bad?

I'm thinkin about getting a 2" coil spacer that is stated to level out the front end with the back end. Has any body tried these? If so... Are they easy to install and do the really maintain the factory ride?:

 

bad. i had them and got rid of them in the same year.

They will level your front end out, but dont expect them to ride like the factory, they are very bumpy and can potentially ruin other suspension parts as stated above by KTP's post. They are a cheap way to make the truck look better, and I myself ran them for awhile, but after learning the liabilities and possibilities of a better ride and better offroad performance... i upgraded.

 

Thanks guys.... Not going to do that!
