if i haven't learned anything else in the30 plus years i have been Wheeling,,, i have learned that no matter what it is they drive, theirs, is the best there ever was according to them, even while they are on my hook!
i have been wheeling IFS since 1990, along with strait axle trucks, both have their place, surprisingly in deep pit mud bogging, not 6 inch mud holes, the IFS will eat up the strait axles, and the fastest of them have both ends set up that way, but it is expensive to build them up till they can handle 700 or more horsepower. I know of one being built right now that is all IFS and will have a 600 horsepower turbine in it, with 46 inch tractor tires on it! i am ready to see it run.
