This Kyosho BRG404 is offered as a pair of shielded 4x7x2.5 bearings, provided as 2 pcs for FAZER On-Road Drift applications. They are intended as direct replacements where a compact, shielded bearing is required.
Fitment notice: the part is catalogued for FAZER Drift series use and is suitable where the chassis or hub lists the 4x7x2.5 bearing size. Always confirm the original bearing dimensions on your vehicle before ordering to ensure compatibility.
Installation notes: seat the bearing squarely into the hub or carrier with appropriate non-damaging tools, avoid applying force to the shield face, and ensure correct axial alignment to prevent uneven wear. Clean the assembly area and inspect shafts before fitting new bearings.
Service impact: installing proper-size shielded bearings restores smoother rotation and reduces drivetrain drag from worn components, which supports predictable steering and throttle response during on-road drift driving. Regular inspection helps spot wear early.
