I've had pretty good luck with these on my E Maxx. The springs suck, smaller diameter wire than the stock E Maxx spring, but haven't leaked yet (6 months). I run 80 weight in them. I'll probably be putting a set of dual rates on in the next month.
Eta and I hate Integy, but these are working for me.
