Re: beaterX project thread
They are duals, I needed them though to handle my lift and not many other people have shown any issues with them. But not a lot of people DD with them and get to 20k miles +.
I think Scheides could've used the Kelford springs as they were designed for his cams but the supertechs have proven themselves for power anyway.
GSC also has some now for the X, not sure on the ratings though, I'd guess good enough for 8500rpms+ and their GSC s2's.
