Hey im new to all of this, just got my 05 Ram 1500 QC SLT with a 4.7 back in Jan. I put a single in duel out exhaust on it and just ordered a K&N intake for it. But anyway i was reading on here about the 4.56 gears and was wonderin where a good place to buy them is? I've got the stock 17' rims with the small tires, idk how big they are.. But would it even be worth my money?? Thanks for the help
