Lockouts are generally a win, win situation. They create much better hookup. It basically turns your basket clutch into a centrifugal clutch. The harder the engine revs, the more the clutch grabs. Clutches last a lot longer...like 3 to 4 times longer. The only draw back I have heard from using these, is under power, the clutch is much harder to pull in. a lot of people i have seen, run only three springs to help alleviate this problem. Most people that have installed them, ould not go back to a stock clutch for any reason.
