By "bolt-on" was speaking only about the lever arm - not the whole installation.There nothing bolt on when mounting The Currie Antirock on a 80 !!
Yeah - I see from your install photo how close the arm is to the Panhard frame mount - very close indeed.
Definitely a factor to consider - change one thing...leads to other mods...so it goes.
I didn't know until this discussion that @jcardona1 had gone all the way to Upper Control Arm A-Frame - to completely eliminate the panhard - Nice! The 4th one to do so as far as I know. panhard frame mount issues - gone!
I'm really just suggesting to carefully consider what kind of "strength" is actually needed in this lever arm situation.So this hollow arm can be nearly 3/8 " wide and just as strong ? I don't think so
The top and bottom surfaces are where the primary strength is needed - in pure tension / compression.
And - the vertical bending force varies from maximum at the spline end, down to near zero at the link end - so it's reasonable to taper it.
The sides are mainly stabilizing the top and bottom - so they don't buckle.
A solid plate arm has a lot of metal in the middle that doesn't give much "strength" benefit.
Of course - there is some side force - due to the angulation of the axle as it articulates - but it's a secondary load factor.
- At full droop the side force is pulling inward.
- At full stuff the side force is pushing outward...so, again no frame clearance risk. - possibility of a crunch still makes me a bit nervous though.
I'm not trying to just argue either - just poking deeper into the design - and all you guys that have posted photos of your installs - are appreciated. Those of us who may one day do this...learn from your examples and maybe refine/improve a little.If you have a better idea build it, mount it and show us !!
