Are they in the upper or lower/ I have been told both.
So can somebody settle it?

I was told stock XR uppers are 1.50, changes are made in the lower to get 1.35 or 1.26.

My (un-educated) understanding is the regular bravos can be changed in the upper or lower.......XR's are lower only.

They only make one flavor of XR upper gear sets (16/19),
( god knows I bought enough of them)
the ratio change is done in the lower

Quin, you should just bite the bullet & put ASD6's on that machine of yours. For all the drives I've busted I could have paid for the conversion by now.
