RCSS T4 Hybrid Ceramic ball bearing set
RC Speed Secrets’ Hybrid Ceramic stainless steel ball bearings are now also available in a set for the Xray T4 series of touring cars. The bearings are about 21 percent lighter than standard ABEC-3 ceramics while making for reduced natural drivetrain drag, better acceleration and higher speeds. The set includes a total of 14 bearings and it fits T4 2018 down to 2015 spec kits.
