I have 1 more set of Richmond 9" gears left from my spare sets
These are a special run of 9310 nickle alloy gears with a slightly harder heat treat than a pro gear.
I used this type gear in my 3470# 4 speed car running 9.60's at 141 with zero breakage, this was a no trailer street car , 126 miles round trip on race day.
small pinion, lightened, deburred, and REM polished.
these gears were installed in a 3rd member and taken back out, they are NEW IN BOX. $250
