"I put this clutch on a 6 1/2 hp gokart, and within 1 1/2 hours, my 55 lbs ,7 year old was able to break this clutch. One of the friction shoes actually broke in half. This is supposed to be heavy duty? I think not. I will be returning and buying a different brand."

"i have been buying these type of clutches for a while and i found a website that said if your go kart haves wheels 15'' or bigger u should use a torque converter clutch and not a centrifugal clutch because it is harder for the wheels to turn so it burns out the clutch a lot faster so i ordered a torque converter clutch and it works ALOT better"

Good product for the price,
January 29, 2009
By ArcticCatDad
from Chugiak, AK
"I use this clutch on a mini snowmachine up in Alaska. My kids have put many many hous on this machine. The factory set up was chewing through chains so I decided to go with the #35 chain and sprocket. The clutch performed very well for just under 2 years. Now I need to replace it because the clutch sprocket is worn all the way down. I cant seem to find a replacement sprocket so I'm going to just buy the whole thing again. I would definately recommend this clutch for mini snowmobile applications."

"I bought the clutch for a 3 wheeled bicycle I was building. The clutch is attached to a 3 hp Briggs and Stratton engine. It works great. Be sure to read the instructions on the package the clutch comes in. It might save some injury."

briggs engine we put on there would be no noise at all. Great clutch.

Centrifugal Clutch,
April 21, 2008
By Muzza
from Melbourne Australia
"I had promised my boys we would build a go-kart. We had an engine, but needed some Go Kart plans, chain, cogs and clutch. Northern Tools had it all. I really mean, had it all. We ended up purchasing a steering wheel, tie rods, wheels, axels, chain, brake and accelerator lever and the Hilliard Extreme-Duty centrifugal clutch. We welded up the frame and mounted the engine. When they say heavy duty, they mean it. The boys are 12 and 14. But I also wanted to have a run on the go-kart. So we need tough components. The clutch is really amazing. There is no gear box, so a lot of the torque conversion is handled by the clutch. We have used the Go-kart for hours on end and the clutch never over heated and always performed amazingly. This clutch is 110% tough and I fully recommend it. And all the Go-Kart parts are exactly what they say and easy to use. Northern Tools made our project end up like a professional job."

"i purchased this clutch recently for my sons 5.5 hp mini bike. when I got it in the mail the hole that tightens it down to the shaft wasn't threaded. when i tapped it my self, then tightened it on it seemed to work alright. After one week of riding, it wore out and broke. I would not recommend this clutch ( though maybe I just got a lemon)."
