This kit is presented as a replacement for Futaba BLS253 and BLS451 servos and aligns with the model references shown in the title. It is intended to replace worn internal gears and restore correct mechanical engagement for reliable operation in model applications.
The content emphasises confirming compatibility and expected results after the swap. The listing mentions AS4149 and EBS3345 as associated references; verify those numbers against your servo's official parts list before purchase to ensure fitment.
Always confirm part numbers and spline counts prior to fitting to avoid mismatches, and keep spare gear sets for preventative maintenance and repairs.
