Installed 4.10 gears in my stang last night, and i cannot say enough nice things about the FRPP gears that was by far the easiest gear install i have ever had, used the stock shims, just turned them around, and BAM .003 backlash, absolutely no noise, and they run perfect first time WOW!!
You made the right choice in manufacturer, a huge battle out there for many who get a motive, richmond or other, ultimately falling back on FRPP in the end..
well, my trap speeds are awsome, so im getting plenty of power, 1st and 2nd have always been pretty useless, but with these gears i can get thru them quicker, and 3rd was always my monster. . now 4th is also. i should be halfway thru 4th when i go thru the traps now. i am figuring my 1/8th mile time should be about 7.3 maybe.
Very nice!
I know with my auto, 4.10s and 28.3" rear tire, I crossed the line around 5200-5500 RPM in 4th(depending on launch RPM, tire spin on the launch and shift points).
