I have 4 new never used 4-link bars. Center to center is 50". They are made out of 1.75 x .250 wall dom tubing with Rubicon Express Super-Flex joints on each end. I have one fully assembled for mock up but never finished my truck. The end part number is RE3792.
I also have the assembly tool for them.
Asking $350.00 for everything. Thats just about what the ends and tool would cost alone. So my hard time are your gain. You get about $100.00 in D.O.M. tubing free. Feel free to make me an offer but don't be an ass and low ball me.
