If you want crisper rolling on your S400 or S411, the Serpent 401123 10x15mm bearings are a reliable choice. They are made to improve rotation and reduce wear, which helps maintain consistent handling across sessions.
Bearings influence how freely wheels and driveline parts turn. Serpent 401123 bearings cut internal resistance, producing a cleaner spin and steadier throttle response. They suit tuners who prioritise predictable on-track behaviour and routine maintenance.
These bearings are sized to drop into the S400 and S411 hubs and carriers with no trimming. Press them in evenly, keep them clean, and apply a light oil periodically to keep them running smoothly in wet or dusty conditions.
