Thats just a rear planet change right John? So it would be 2.28/1.45/1:1

7% just doesn't sound like a lot to me but it may work.

The 2.28 is a helical cut correct? How much HP will it handle (I know thats a tough one to answer LOL) Is it steel or Aluminum? I guess if its as strong as the stock 4 gear rear planet we have now it should work fine.
