Was asking what the above forces look like using the TG/PSC rams with smaller rods?
According to an online calc, it basically doubles the "rod side" pressure...
Pressure acting on rod side
2" Piston diameter - d2 (in)
1.5" Rod diameter - d1 (in)
1300# Cylinder pressure - P1 (psi)
Force Rod Side - F1 (lb): 1787 (2297# delta)
Pressure acting on rod side
2" Piston diameter - d2 (in)
0.75" Rod diameter - d1 (in)
1300# Cylinder pressure - P1 (psi)
Force Rod Side - F1 (lb): 3510 (574# delta)
Pressure acting on opposite of rod side
2" Piston diameter - d2 (in)
1300# Cylinder pressure - d2 (psi)
Force Opposite Rod Side - F2 (lb): 4084
With the above numbers, the force delta for these smaller rod rams are a lot less, so guessing that equates into a "less noticeable" L<>R steering difference running a SE ram?
Also my concern, since stock Jeeps using 11/16" TREs/etc. are obviously a "weak link", 3/4" rods in these rams cause me to wonder about failure rates.
Meaning, outside of NON-contact (bashed into rock) & installer (bad placement/geometry) issues, are y'all seeing regular failures? EDIT: I see @Chris_Keziah was referencing the TG w/ 1.125" rods...
All this is finding my own "warm fuzzy", given the on-road part deciding between:
- 1.5" rod (harder to bend) w/ what appears to be VERY noticeable L-R-performance = keep the SC ram
- 3/4" rod (mounting better be dead nuts or) w/ what appears to be 400% less noticeable L-R-performance = start over
Have yet to see a failures on the rams and they've all been through plenty of abuse.
I don't think any of the double ended rams come with a shaft smaller than 1.125" I feel as if you're over thinking this. Set up right or even remotely right you shouldn't have any issues with an off the shelf PSC or TG ram with 3/4 heims.
If you're wanting to run a SE ram the one meant for full hydro are 1.125" rod as well. I'm not a fan of SE rams but tj get do have the advantage of packaging over a DE ram. Also for the sake of discussion the ends smallest bore offered for full hydro specific rams is 2.25"
