Currie J arm question
What is the bend radius and degree of arc of the Currie adjustable J arms? For degree of arc, straight line of the arm to center of mounting bolt is fine, with the pivot point being the center point used to calculate radius.
I'm brainstorming some new rear lower arms by flipping the J arms over from their usual mounting method and attaching them to the front of the axle. Trying to calculate clearance and those two measurments would help a bunch. Any thoughts on this? A bend in the arm shouldn't change my suspension geometry, as long as mounting locations are the same as with a straight arm.

longer J arms

So you want to shorten the arms back to being the same as stock, thereby losing the benefit (longer radius) of the J-arms? Or are you planning on pushing the frame mount farther forward, and just want to run the arms upside down to benefit from higher clearance arms?

Blaine and I talked the other night, and we kicked a couple ideas around including reinforcing my RE arms by sectioning them, sliding some tube (or solid rod) inside, welding them back up, then getting them bent near the axle end into a custom J at whatever radius is needed to make it fit.

Is this correct ? If so, what benefit(s) are you proposing this will offer over just a straight arm fastened to the front of the rear axle ? Fred

The standard configured J-arms work best if kept shorter than a conventional long arm. Otherwise you defeat the purpose and wind up with a lower physical arm angle even though the effective angle is improved. Flipping them will help, my only concern is gravity pulling the arm over to one side or the other.
