Can the 44 for a 9". A strange "Drag Gear" ( 9310 steel) will hold up as good as any. If you have the gear lightened it's good for 50 passes. If it's a standard gear no more than 75 passes. You may get a little more out of it with only 700hp and 2,000lbs, but the gears start cracking real quick after that many passes.
You running 40 hawgs or 39.5 swampers? Swampers bite a lot harder than the hawgs.
