Like i said i would go with redcats big bore shocks. Its 30 bucks for a great set of shocks that work great. Before the shocks were real bad, didnt hold oil, and the springs were real loose. So i put shock spacers on them, but when the oil leaks out, it makes it real bouncy, there isnt oil in there to slow down the shaft. There is a guy by me that is a dealer for redcat and he said he rebuilds them and they work great. But i just got the big bore and they work real good. Threaded shock bodies and stuff. I'd check em out, if you can get a good deal on something else then cool, but with those you posted your gonna spend twice as much for the same thing basically. but thats just my opinion
