Keeps them motors cool even when riding really hard for over 2hrs still kept them motors cool love the heatsinks

This heat sink didn't work on my application, due to where the motor mounts to the gear housing, it doesn't allow ample room to fit the heat syncs. So I couldn't install these. Please check your application setup before purchasing.

I am please, these worked great for my application

So far they have worked well. My son drives his power wheel a lot and for long periods. I had a 550 motor over heat and I had to replace it. The heat sinks have helped keep the motors cooler

Well made. No instructions. Would have been nice to show a picture installed so I didnt have to R&R it for clearance.
