Not true. You have to disassemble the CV and reassemble with the flange style end, which is a pain in the ass on the bench - forget trying to do it on the trail.
There is a reason the majority of jeep owners spends $250 to $350 on Tom Wood or JE Reel driveshafts, and its not us trying to show off how fat our wallets are; you get what you pay for.
Stock front driveshafts have puny slipjoints that wear out and cause vibrations LONG before an upgraded driveshaft will, and the slipjoint is at near max extension at ride height, so you will have minimal contact and increased wear to boot.
