The SPC xAxis Sealed Flex Joint is a sealed cross-axis ball joint designed to upgrade rear control arm links, providing reduced compliance versus rubber and increased angularity versus urethane. With sealed ends to keep grease in and a polished ball for durability, this 12mm x 57mm x 40mm joint serves as a direct upgrade for compatible BMW rear control arms and similar link applications.
