Two of my shocks have been bent so far and I was thinking about upgrading to aluminum piggy back shocks. Will these new shocks not bend as much? Also, are my shocks bending because I'm using the wrong shock oil? So far my T-Maxx 3.3 has had about a gallon through it and I've been using the stock shocks and haven't oiled them. What type of shock oil should I get if the roughest stuff I go on is low grass (like a football field). Should I get different springs too? I am using the stock red traxxas springs on all 8 shocks.

P.S. The bending isn't like a 90 degree angle, it is just a slight bend which causes my truck's steering alignment to go off and is bad for the other shocks.
