Got the new
5.71gears installed today.
I would not recommend anybody else use 5.71's and defiantly not Precision Gear at all. The work I had to do to get the pattern anywere close was BS.
You should never have to use .218 worth of shims to set any gear and the pattern is spotty, it doesn't use up the whole tooth.
This is only the second set I tried, the first I stripped the ring gear bolts out and sent them back.
It is early to tell, but looks like this gear ratio may help as I can now stay at speed in 4th gear and even think about using 5th.
