Xray introduce new aluminium rear uprights for the XB4 line of 1/10th scale buggies. The parts are of a new design with vertical ball stud mounting positions that allow for easy roll centre changes by adding or removing shims under the camber link pivot balls. The hubs also sport a total of five different mounting positions to alter the length of the camber links in order to further fine-tune the camber gain characteristics. On top of that the uprights allow for a wheelbase adjustment range of 4mm. The black anodised and laser etched parts come separately for the left and right hand side of the vehicle.
