they look the same to me anybody have any more info

 

The hpd are a harder rubber.

 

I like mine. After I got my HPD mounts on the gas quit leaking out of the bowl vent on the carb so much (bouncy bouncy from the paddles). Weird I know.

 

I was wondering if they would stop the fuel slosh. The 400 motor shakes around like crazy.

 

mine bounced around a lot too and while I was tearing my engine apart I found out why. the top motor mount didn't have a nut on one side. Guess the guy that had it before me forgot that nut. on the other hand sometimes you feel like a nut sometimes you don't.

 

no,not the same compound at all especially if you go for the 90 durometer
or more,even on sleds polaris put very weak motor mounts,you need to go
aftermarket and that is simple like this,on a modded engine the stock mounts just can't hold the engine and that is the worse thing,they wear out pretty quick.
