Toobuilder Well Known Member Feb 2, 2018 #2 Are you asking about using a standard hub Hartzel + a spacer instead of the usual "extended hub" Hartzel?

F1Boss Well Known Member Feb 2, 2018 #3 No extension needed Buy the right prop - "M" hub - and you'll be fine. No extension needed.
G Gusmax Well Known Member Feb 2, 2018 #4 I just looked this up on the Hartzell website last week and if you already have a standard "C" hub like I do, then you will a 2.56" extension. 6.75"-4.187"=2.563". Please look it up yourself and confirm I have it correct? Cheers, Phil
