The stock caps are also junk. I ended up going to some STRC alloy caps which improved the situation greatly... but then got rid of the stock shocks altogether as they were pants. Trust me, you could tie a knot in those shock shafts with your bare hands if you tried hard enough.
Yeah I was a little disappointed from an active thinking company not to do a bit more testing, but what the heck, can't expect them to think of it all !!
The Slash is nice, but lets not forget what it is, a hacked up rusty/pede hybrid with a new chassis. Apart from the T-maxx, Jato and Revo, Traxxas have essentially done nothing but tweak old designs for the past 15 years. I'd of thought by now they would have perfected the Stampede/Rustler parts enough to actually make a truck that works out of the box.
