No, not any more than normal. SOmetimes its a PIA and have to play with it to diff lock unlock. I am bad about stopping first to engage. Key off rarely to reset it to work. I have had eps light stuff on old trex and it turned out to be weak battery. Spacers do slow up the EPS but never been a problem in any way running spacers except more mud flying. Being 65 wide helps on sidehills and corners and wheeling rough big stuff.
