I have a 1.5" leveling kit on my truck and it is still not completely level with the front. I was wanting to buy a 2" leveling kit but am not sure if buying the coil spacer or getting bigger springs would be best. Any suggestions? Also, When I had my 1.5" leveling kit installed they said it was bottoming out which doesn't make since to me since the shocks should have about a 7" length to them. Should I also buy some longer shocks?
