4000 Series Servo Case Set for JR Propo - JRSC4000  [JRSC4000]

Scale-Accurate Servo Case Replacement

This RC replacement housing matches the footprint and mounting points of the specified JR Propo servos, intended to return a damaged unit to service or to secure a freshly serviced servo. Keeping the case true to the original dimensions helps maintain gear mesh and reduces unwanted movement under load.

Fitment should be completed in a hobby workspace with standard hand tools. Transfer all internal parts carefully, check screw positions and post conditions, then verify horn orientation and end-stops before reinstalling in the model. The case assists with predictable responses during tuning and on-track adjustments by limiting extra play.
