SPC’s xAxis Sealed Flex Joint for Jeep JK rear upper control arms is a direct replacement for the OE rear UCA bushing, reducing compliance while increasing angularity and durability versus rubber options. The sealed design retains grease and repels contaminants, and the polished ball surface promotes smooth movement—offering a serviceable upgrade for Jeep JK rear suspension components.
