I have an '08 qc big horn 2x4, and I wanted to lower it. I thought about the 2/4 kit, because the 32.7 inch tires are so huge. I think a 2/4 is just about my limit on the lowering. Has anyone went lower on their '08? I found the 2/4 kit for $500ish. If I get smaller tires, the dealer can still reprogram for the different sizes, right?
