OK I have a 2008 Silverado I don't know much about lowering trucks, and i'm on a budget. I found the one i want in a truckin magazine, its from sport truck direct. cost of the kit is only $199, and it comes with front springs and a flip kit. i called them to see how much it would lower my truck and they said its a 3 5 kit with everything i need to lower my 08. what i want to know is I have Boss 24'' with 305 35 24 tires so will this fit without rubbing? Also want to know about a flip kit, are these a problem i mean do i have to worry about my rear end falling off or any other problems with it?
