Breaking rear shock towers - likely suspect?

[suicideneil]

I've seen lots of shock towers brake in the same place over on the numpty forum. Seems the shocks actually bottom out before the truck does, so the upward force of the suspension just sheers the towers off after a few landings; stiff springs would actually be the best solution believe it or not.

Try using 4 of the trinity XXX heavy blue springs, usually works a charm if you do much jumping. RPM towers would be better than stock, but then the bulks might suffer instead at the attachment point.

Well, he busted another rear shock tower yesterday. This is three for three now. His suspension is quite a bit stiffer than anything I ever ran on my Emaxx's, but I didnt do any jumping like we are now. Between this and the issue with his HV system, he's feeling quite frustrated at the moment, especially since the economy is hitting his business quite hard, and he doesnt have the funds to keep up with me (kinda makes me feel somewhat responsible).
I think I made the mistake of actually reducing his spring rate while we were doing the FLM conversion. Right now he is considering going to aluminum shock tower and bulks. I'm somewhat hesitant to have him invest that kind of money into the truck, since we havent really figured out the cause yet. I'd almost rather see him take that money and use it on a truggy conversion.
