I have that full organic clutche in probaly 15 trucks and a few of them are over 400hp and i have not go a single call with one issue with that clutch! If you want to abuse a clutch spend the extra money and do it right the first time and dont blame the product when i KNOW what its capable of. Treat the clutch right and treat it for what its rated for and it will treat you right! I had a Valair single cer/kev and was far over the hp limit and never slipped it once.
