Congrats!
Simply amazing. 90% of the pullers swear you can't even make the sled move with a 2WD.
a lot is set up too, 4X4 guys got 1000# or more on front end, Kurt doesn't have the 4wd weight so he's got 1500-1800# sitting on rear axle, 5" higher hitch will help a lot on the short sled chain.
the driver of a 4X4 is used to coming out hard so if he loses the front axle most just hammer it and spin the tires. if they feathered it they could do good too. get a 2wd on a muddy or sandy track and it won't pull as good.
