This Short Shaft kit is engineered to withstand the increased torque
generated by the extreme reduction of the TeraFlex Low231 4:1 Heavy Duty
Transfer Case kit. This kit also eliminates the need to lower the
transfer case in most cases by increasing the rear driveshaft length by
four inches. It includes a larger output bearing and rear housing. This
kit must be used with a CV style (double cardan) driveshaft. Note: Fits
XJ Cherokee 231-J transfer cases w/ vacuum disconnect.
