UMI Performance Thrust Bearing Kit Viking Coilovers and UMI Coilovers + Spanner Wrench

The thrust bearing kit is designed to be placed between the spring and the spring seat attached to the coilover shock. This allows for easier adjustment since the spring seat is rotating on a bearing. This kit is recommended for easier adjustment but is not needed to complete the installation. We do not recommend adjusting vehicle height on the car without using a thrust bearing kit.
