Technical Dead X

just be reading Hop Up special No5 and there is an article about a guy scratch building a speedster but I don't understand part of it and I quote "Friend Mike Bowling donated a heavily heated plus bent Model T rear spring that negates having any real suspension but being at Dead X meant better take off and no wheel hop" unquote.
What is Dead X tried googling it but all I get is not found. I am really curious about this can anyone fill me in on this please.

Maybe another term for a dead perch?

 

@mike bowling is a member on here. He should see this alert to this thread and answer your question.

 

dead center is what dead X means, I think

 

I was thinking that it meant "dead nuts" as in "exactly on". Exactly on what? I don't know.

 

I think it means no rear suspension Like a dragster or altered

 

We could ask OJ...what? too soon?

 

Spring was heated and bent so much its Dead on the Axle.

 

Now I want to know, too!

 

I'm in with 'straight across with no arch'....... but that's just a guess.

 

"I heard it on the X".

 

Ray is fatherray on instagram just ask him. I don't think he's on here ever anymore?

 

Up here, it was ''dead ax'', as in dead axle, meaning no travel.
