What are the measurements of the superflex joints? What size bolts do they use?
Rubicon Super-Flex joints are built to fit into factory bracketry. Small joints, designed for use in the upper control arm location are 2″ wide, ear to ear and utilize a 10mm thru bolt. The large joint for the lower control arms are 2 5/8″ ear to ear and utilize a 9/16″ thru bolt. We recommend using only grade 10.9 metric bolts and grade 8 SAE bolts with our S/F joints.
