Just bought another set last night because I'll be building my shocks for the new Revo next. I really think they help a ton, I think they're more for the track but I like how they have made my revo act after a large jump, it just doesn't bouce around any more. Generally feels much more stable and has reduced body roll. I do not run sway bars on my bashers to keep everything nimble, the valves have acted like a very light sway bar in effect.The truck seems to be more planted.
Here is whom I purchase from and they ship world wide
