Yep it's 3"
you can actually buy a 2.85" size from Metco as an upgrade but don't think anyone is running it. This chart from Lingenfelter is really useful too... http://www.lingenfelter.com/sites/lp...ey%20Sheet.pdf

hmm I though it was 2.95 which does round to 3 but I didn't think it was 3.
all of the boost charts I have seen list the stock at 2.95 though.
