_dV - well i didnt use those pink+yellow sping set up as my Flux Baja 5b will be between 6kg -7kg heavy, so i will not use them.
But maybe good for heavy loaded trucks..
Well the thing is...DB are made to transfer the power. Well i didnt see no cups that can take bigger "DB ball ends" so there would be no point for manufaturer to make those bigger or thicker...but thicker DB in a longer truck like 5b is always welcomed in my

.
I am thinking to put 1520 or 1717 in this thing... any advice?
