Deffo 4" ....if you measure the tubes should read 105mm............that's why their called DH down hill.............long travel was a tiny 4 inches then.....mine were anyway
Sure they measured at the tubes 105mm just over 4" but in reality like most forks you wouldn't get full travel so i guess your right about 3" actual travel would have been realistic..............sorry, always saw them touted as a four inch fork
