Where do you get the Ferrea? How much? Do they have them for the lt4? Can you use 918's in lt4's? The guy I bought my car from said he has heard a lot of problems with the 918's breaking. Anything to that? 918's are from Comp Cams right?

I only got about 10k miles out of my Crane duals before I had a failure(s)

We prefer the Patriot doubles over just about everything else out there. They are rated to .650 lift, but we've run them past that with no issues 
We stock them, so shoot me a im if you need a set If you order online they should ship same day

Patriot Dual GOld Springs. I got them pressure tested. They are just as good as the rest. but cheaper
The whole 918 breakage thing is a bunch of crap..it's all he said she said crap. There were very few failures when they first came out..since then..no failures. Also the whole "gotta change them every 15K" is crap too
