I have stock shocks on one of my maxx's and that thing has been around for almost a year and the shocks are still great. I dont see how you go through them in a few weeks. I mean yeah if you are crashing alot then they wil bend sometimes.. I had a front end of my classic tmaxx get rann over and only bent one shock and brock shock tower.. But on topic I think the only way they could change it is to upgrade servo's, change rims and tires, maybe a new paint design for the lid, and maybe a couple small things that I am not thinking about.. I honestly think the only reason why they do little things to rigs and then reintrodice them is to get them flying off the shelvs again after people slow down on buying them... just my .02
