    Are the 9.5 gears any better than the 9''..... looks to be only a 1/4'' and 200.00 deference.

    what are you running it in? I run 9.5 and mod 10" in my Pro Mod. 9" in will not live very long.

    Going from a 9 to 9.5 made a huge difference in gear life. Have to grind some cases to fit. Some can't be done.

    Jim it is only about .250 difference the last time I checked... My 9.5s lasted quite a bit longer. if you keep the shake to minimum the 9" wasnt so bad, but shakin' to death cooked them pretty fast!! :D

    Who sells them 1o" gearsets? Ratios available? And i suppose they fit an ultracase with some case grinding?

    I bought mine from MW. They will fit in a 9.5" fab housing they take a little off the back of the 10" to get it to fit. I like them alot.
