Hood Strut Replacement 2005 Ram

I thought my 03 hood struts were good until one day in the rain I raised the hood, stuck my head under the hood and it came down on me, wet hood weight? With that grill hanging off the hood it feels like you are being eaten by your truck! At the recommendation of one of the Dodge/Cummins sites I installed struts from a newer truck, apparently the newer hoods are heavier? Now when my hood is opened about 10" it pops open by itself. Before I had to open it all the way. The new struts are about 3/4" in diameter, the old ones are about 1/2" in diameter.
