The xAxis Sealed Flex Joint is a technology step up for suspension joints and linkages. xAxis delivers reduced compliance vs rubber, improved durability vs spherical bearings, and increased angularity vs urethane. Featuring sealed ends to keep grease inand contaminants out, a highly polished ball, and 19deg of articulation, this cross axis balljoint will meet the most demanding requirements. This xAxis has been specifically designed for the 67660 Subaru Scion rear control arm, but with a 12mm through hole, 42mm width and 40mm OD it can be used in many applications and fabricated linkages.
