I have a stage 3 2004R / 455 infront. looked at a few before I made the decision. .67 OD is hard to beat and depending on its orginal application, you can get slightly different first gear. As has been said, youll need to make sure the TV is adjusted correctly.
Im not a racer and Im in category 1, was in the "plan" I run 3.42:1 psi disc rear, and plan on 14 miles to the gallon too
