Custom 4 link suspension
 

For my 12v ramcharger project, I want to build triangulated 4 link setups front and rear. It's gonna be clearing 38.5s and really long links. The plan is for it to be very off-roadable and slightly streetable. I'm having trouble finding a source for weld on link ends to build the links from. The only one I've found is using heim joints all around. I'm not against heim joints but if used on both ends of the links wouldn't it ride very rough on the street?
If anyone has a good source for parts please let me know
Thanks
