Re: What is a screw jack suspension?

Just a guess but Stock Cars and dirt track cars have a big screw on top of the springs so they can adjust the height/load on each wheel. I am guessing something like that so they can adjust the right height.

Re: What is a screw jack suspension?

I saw a 56 ford pickup once in San Diego that had (claimed) Nascar suspension where he had s crew type cranking mechanism on all fours to adjust the suspension. AKA Wedge adjustment, simply refers to adjusting the amount of force that bears down on a tire's spring.

Re: What is a screw jack suspension?

This is a kind of screw jack or weight jack. You will see in the picture the cup the spring sets in and an all thread bolt sticking out the top that can be twisted to raise and lower the height of the truck. But more importantly it can also "corner balance" the truck for desired weight distribution.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: What is a screw jack suspension?

hey I have a 50' olds. it has fatman spindles also. I haven't gotten it on the rd yet this year.

These cars have factory "truck arms" with rear coils to begin with so a setup like above would make sense. I've heard 67-72 c10 rear coils will lower them 4-5" in the back. Haven't messed with that yet. Plan to do a gasser type build have a hopped up Cadillac 472 for it.
