Not avoiding it, I thought you could learn something new today.
Then please teach. Because it really seemed like you where avoiding questions and answering with half truths.
There you go.
A lot, do a search on the various companies that are out there that offer a radius arm set up.
What other companies turn the stock length arms into radius arms?
Again it has been used in OE applications for a LONG time, and in aftermarket applications. There is a reason for joints that flex
What OE Radius arm setup most resembles the Jeeps axle mount locations separation and offset?
How does the Jeeps axle mounting locations differ from most OE radius arm designs?
Do radius style upper arms as found on a Jeep twist and push the axle in opposite direction when the suspension flexes (1 side up/ 1 side down)?
All of those OE applications where designed around a Radius arm suspension and have axle mounts intended to be used with a radius arm. The OE applications do not take an axle setup up for a 4 link+ trackbar suspension and try to turn it into a radius arm suspension.
What is the cost involved \ compared to a radius style set up?
How much will it cost to replace and have a new upper control arm bracket welded on after a set of radius style arms twist and rip it off?
Do long arms compared to short arms provide less bind for a given amount of axle travel?
Would long arms allow more axle movement with less twist/pull/bind the upper arms create when compared to stock length/ short radius style arms?
