Will these shock pads work with these trucks?

Ok, so im ordering my trucks for my new double drop (drop through/ drop deck) longboard and I also would like to have an set of shock pads on my board to protect it. I can only find one place that isnt charging for an shipping and I belive they have what I need, but can anyone verify if these shock pads will work with bear grizzly 852's? thanks http://motionboardshop.com/shock-pads-1.html
