If you can't find a trade let me know and I can set you up with the gears and a Eaton/Truetrac Positraction. We have them in stock and ready to ship.

What diameter are your rear tires? That seems aweful high for 3.42's.

I ran 4.11's in my 9" and a TH400 and didnt rev that high. (Either that or you have a loose converter.)

If thats the case, you may want to look at something other than taller gears. Play with these calc to see whats up.
