The XRAY 379001 X1 Ball-Bearing Set is aimed at hobbyists who want to lower drivetrain losses and secure smoother acceleration and cornering behaviour on track or rough surfaces.
Components in the XRAY 379001 set are high-speed ball bearings matched to strict tolerances so rolling resistance is minimised and spin consistency is maintained lap after lap.
Steering bearings are lightly oiled using AeroShell Fluid 12 to preserve smooth steering action and reduce early wear, keeping handling predictable across sessions.
Every bearing is measured and inspected to meet XRAY inspection criteria so you can expect reliable fitment and uniform performance when installing the set.
