Fits ok blades are very thin, if you're not careful installing you can easily bend a blade and then have a vibration problem.

Bought this fan to replace the fan clutch fan that the mechanics put on my engine that sawed into my brand new radiator! My 1981 Ford 4.9L straight 6 F-100. Ford didnt design that year model model with an engine fan clutch! After buying a universal CHEVY all aluminum radiator that was closest to the OEM Ford radiator in size and inlet/outlet locations because 42 yr F-100 4.9l radiators are VERY EXPENSIVE IF YOU CAN EVEN FIND ONE. So after buying a 2.5 in spacer and the correct OEM radiator shroud for that model pickup truck I'm back in business. The 18" OEM sized flex fan is very strongly built and resisted bending by me pulling and pushing on it while tightening the mounting bolts during installation. It moves a lot of air and my truck stays well within the operating temp range. I am very pleased with my MADE IN AMERICA purchase!

Good looking Fan, good price. Used it on a 76 bronco, after adding AC and an extra belt needed it for clearance. Worked out great

NO the fan blades do NOT flex and flatten out like other fans do. The blades are ridged. THese are not designed to pull more air then OEM fans. Their designed for higher RPM rating. 8k rpm. My application is as follows. Hot cammed 351 cleveland motor, I changed to a smaller pully. Almost doubling the water pump speed, and also fan speed. Was way too fast for OEM blades. So I needed high RPM fan like this. Works Perfectly. As intended. Their not intended to solve an overheating problem. I changed pullys to increase water flow to solve that. Which also worked out perfectly. I have a 450hp Cleveland that runs at 150 degrees as a result. But that's not due to the fan.

Installed easy, not sure if it clears the shroud enough, soon to find out. It looks good though

Installed this on my big block chevy. Looks good and seems to work just fine. Not sure if moves more/less/same air as the stock one but I haven't had any issues
