Well I have put around 15000 miles on the clutch so far, it's still doing great! I did finally get on the dyno couple months ago and hit 560hp with intake, h&s, and exhaust... i daily drive on the HD300 tune and im not always easy on it, have done some towing with it amd the clutch holds great! There will be a dyno day December 1 here in midland, tx at hoss outfitters! Hoping to get some better numbers since!
