The Kyosho BRG404 is a twin pack of shielded 4x7x2.5 bearings, supplied as 2 pcs for FAZER On-Road Drift models. They are designed to replace small rotating bearings where a compact, shielded solution is required.
Compatibility reminder: this item is catalogued for FAZER Drift series use and fits applications requiring the 4x7x2.5 form factor. Verify the bearing size specified by your chassis or hub before purchasing to confirm suitability.
Fitting advice: press the bearing evenly into the hub or carrier with non-marring tools, avoid pushing on the shield face, and check for correct axial alignment to reduce premature failure. Maintain a clean environment and inspect mating parts for damage prior to installation.
Tuning notes: installing fresh shielded bearings of the correct dimension can lower drivetrain friction and sharpen rotational response, aiding consistent control inputs for drift tuning. Regular bearing checks are a simple tuning upkeep practice.
