radius rod: OEM vs aftermarket w/lockout
 

I need to replace a radius rod and am wondering about benefits of aftermarket.

I know that heim joints (where applicable) are generally superior, but in some specific areas they seem to offer far less benefit than others, so I'm wondering....

Does the front of radius rod experience enough force that it can really benefit from lockout bolt/washer and/or a heim joint (like camber arm does)?
