When a suspension lift kit is fitted it increases the distance between the transfer box flange and the diff flange. This increased distance can cause the prop shaft to run out of spline travel. Fitting this 10mm prop spacer helps return the prop shaft to its normal operating length therefore allowing full spline travel which also helps prolong the life of the center bearing and reduce the characteristic "binding" of the yokes when a prop shaft is over extended.
