These Hayden fan clutches look to be of good quality. Bought this to install on an older Mustang. Issue now is I can't find the fan blade that fits. I got a fox body fan blade but its backwards and wrong bolt pattern. I think this is the correct unit for my engine as the water pump bolts line up. Just wish there were more options and better way to find the fan blades as Hayden no longer makes fan blades after calling the company.
Looks to be of good quality, and works smoothly. It is a little short for my application and keeps the fan about and inch back from where it should sit for optimal cooling, but I will extend the shroud to counteract this issue. My particular application is a 1979 Mercury Cougar Xr7 with the Ford 302, and originally came with a steel flex fan and aluminum spacer from the factory.
