So I am looking at 1.5"x8" rams on surplus center's website

http://www.surpluscenter.com/

And I see two 1.5x8 rams...

one with a .750 "rod"

http://www.surpluscenter.com/item.asp?UID=2005070413442005&item=9-4410-08&catname=hydraulic

And the other with a 1.000" "rod"

http://www.surpluscenter.com/item.asp?UID=2005070413442005&item=9-6645&catname=hydraulic

The wierd thing is the 1" (0.250 larger than the other) rod is rated at almost double "push/pull" power. My understanding was that the more fluid in the ram, the more power it would have... Does this make sence to anybody?

The max pressures for those two rams are different. The 1" version can handle 3000 psi and the 3/4" one only 2000 psi. That is the big difference, also the mounting ends are smaller on the 3/4" unit

Piston area is what counts for force, i.e. pressure x piston area minus rod "area"

This is a reply I got at a local forum

but if your doing assit you want a ram that will be able to push/pull relativly the same. these once push alot but have almost half the amount of pulling force. Look into a better quality ram that is closer to equal for each direction. Forklift or bobcat rams are almost equal, also the ones that have the 4 rods that hold them together usually are aswell.

Any truth to it?

I'll be upgrading to PSC steering shortly... so which ram would you guys recommend?


Sorry I know this is a newb sorta thing... I have done some reading (searching) but I figure live advice might be better.

if you are going with PSC setup, just get their matched ram.
