Hey guys, quick question. I have a 1997 F250 extended cab. Just got a Dana 60 and wanted to lift it. Now i was told to get a RSK from sky manufacturing and 4" rear blocks from a F350. Well i got blocks yesterday from a guy on craigslist for 20$ and got home to check out sky's website. Well they offer a 3inch RSK and a 5 inch...I've herd the d60 will raise my trucks nose up 2 inches. So if i get a 3" RSK and my blocks out back ill have 5 inches of lift upfront and 4 out back...Or am i missing something? Thanks for any input!
