well these seemed nice at first but after 3 months they squashed flat and i had to put the stock ones back on. i used these on my stock 2002 hd softail thinking they would last longer than stock but they didnt. i torqued the nuts down 36ft lbs like the manual says so i guess these arent that tough. oh well i guess ill stay with the stock ones that have 60,000 on them with no marks or damage. you live and learn right?
