You won't lose as much with our Kevlar clutches. He lost about 50% with an oem clutch. He probably would have lost only 10-15% with ours. Our Kevlar clutches do better than oem clutches as far as reversing uphill but we still recommend that you avoid reverse uphill if possible.Do you lose that much clutch with your Kevlar clutches as well? How do they do reversing or on a hill?
