If a rock or something flies up the boot protects the shaft and the shaft seal. Without the boot there is a chance that the rock will hit it. Although the shaft is nitro steel so it is hard to prevent chipping and pitting, and the chance of something hitting the seal is small.
With the OUO blocks you can run either standard 5/8" diameter u-bolts or the 3/4" diameter u-bolts.
