Why 1/2"? Wouldn't that increase each inch by like 100 lbs? And we run IMCA tires in AZ.

1/2" is what it took for me to get the travel where i wanted it...less was just way to soft and to much pinion travel...plus big difference in location...your in AZ im in IA so...since kraftkar7x is in IL id go with more preload since the tracks up here have some more traction in them

10-4 thx for the explanation. I was goin off of what some local people been telling me. It's about as slick as slick gets right now for the winter series so I'll keep an eye on the travel see what I'm gettin in the slick with 1/8"-1/4".

i like to stay with 1" - 1 1/2" of travel otherwise your taking alot of angle out of the jbar with all that movement
