Knock off cal-trac bars.....hmmmm

Just got my knock off cal-trac bars in and they seem to be very good.. heavy duty, decent welds,and powder coated...says made in New Jersey...only paid $155....and if I could have affordedthe real deal $476...I would have gotten them...my question is should they work with oem leafs or are mono-leafs or split mono leafs required...kinda on a budget and need advice....going on 71 duster with factory 6 leaf 340 springs....

The CalTrac or like system works with any spring. John Calvert will tell you that the monitoring works best. Work actually does, IDK. There’s a few guys here running them, they can tell you best. From what I remember, (that means double and triple check me) the mono spring was better from reports here.
That's what I have, nice stuff. Works with any spring.
