The 3RACING BS-501X/V1 Ball Bearing Set is intended as a performance-focused replacement for the TRF 501X factory bushings. This set reduces internal resistance in rotating assemblies, improving throttle response and consistency under load.
Precision bearings lower mechanical losses at axles and gear interfaces, cutting heat and wear. The BS-501X/V1 is dimensioned to match TRF 501X interfaces, enabling predictable setup changes and easier tuning for competitive running.
Use a proper bearing press or matched socket to seat bearings without distorting the outer race. Verify axial and radial clearance after fitting, then apply a light race-specific oil. Monitor bearings for lubricant degradation after high-hour or wet events and service as part of routine race prep.
