loop it Member 62 Member For: 10y 3m 16d Posted 09/03/15 08:45 AM Share Posted 09/03/15 08:45 AM (edited) I was chatting to an old guy today who used to build tail shafts for trucks and anyone who wanted them built, drag cars etc... anyways he was telling me they would up the diameter to cope with higher speeds and the thickness for higher hp ... what sizes are people using for their cars ?
