Gen-TT LSX Boost Proof Fuel Rails How many times now have workshops seen aftermarket LSX fuel rails bend the brackets and push the injector O-ring out with the resultant big fires as soon as boost is added? I know a couple of workshops that had some close calls and rung us to order our new 'boost proof' fuel rails 
CNC machined fuel rails with nice deep injector recess points and threads for Dash 8 fittings on each end are standard with every kit, as is the billet fuel rail mounting brackets which are stronger than any other LSX fuel rail bracket commercially available
Bolting rigidly to the fuel rail our mounting system makes the rail simply unbendable which means no more problems or worries with high boost applications in LSX forced induction engines :teach:
In stock now, $245 plus delivery

Zero but your fuel rails look nice.
On a plastic intake at 60psi you can see the rails move 1/8 of an inch when you turn the pump on. My rail mounts arent going to break but I'm paranoid about the inserts in the plasic intake letting go one day.

I think they look great and they are a great price but I was simply answering the man's question.
Nice, I know that my aftermarket billet rails leak at the injector O rings, just a small amount to collect dirt and dust...but it does unsettle my nerves.....and I don't push big boost, most i've put through this engine is 17psi.
I've always chalked it up to my braided crossover line being to tight between the rails and causing some "warpage" under hard use....and always seem to put it on the back burner on the fix it list. But if there has been issues with rails doing this then it does concern me.

I seen one, someone I know used ford rails (they fit LS1s) and used some 1/8" aluminum strips bent in an 'L' shape, that worked for about 10 minutes. I remember a couple early aftermarket rails that had skinny little brackets that bent easy - dont remember whose.
The rails I have use billet brackets and I could use them to lift the engine out if the intake could take it, maybe they have some crummy aftermarket LSx rails down under
