I had heard that I would have to change some of the parts. Just compairing the cost of the new ones vs upgradeing them and not having to try to sell the 2's.
4x4dually, Not sure what you are running now but you are pushing more to the ground than I am. If I can I want to upgrade these, but If I can't I will get in touch with you.
I'm runnin' Jammer 4's (125hp). I'm just looking for some cleaner burning sticks around the 100-125 range. Ideally I would like to trade straight across with someone but I doubt anyone would trade me Jammers for Mach's. I'm to the point where I want to get better economy and less smoke but stay in the 400-450 hp range.
