I have the same truck and before I lifted my 03, I bought a set of add leafs from our local spring and brake truck shop here in the U.P. I personally don't think it matters what brand you go with. I was able to run 305's on my stock alloy's- 315's are to big. It barely touched the inner plastic fender at full clock. Not enough to tear anything up. It looked really good, the way it should have from the factory. The 265's that were on it looked rediculous.what is the recomended leveling kit i have a 2003 4door 4x4 lariat and what is the biggest tires i can fit with it?
Thanks for feed back
