I am thinking about putting 2.5" spacers on the front of my 2003 Dodge Ram 1500 Quad Cab 2x4. This will raise the front of the truck so the *** end doesn't look so jacked up. Will this effect the ride significantly? Also will this limit the towing abilities in any way? Some people have said if you put spacers in the front you have to change the shocks is that true?
