JR Propo Replacement Servo Case Compatible with 4000 Series JRSC4000  [JRSC4000]

Spare Housing for JR Propo Servo Range

This replacement case is crafted to mirror the original mounting layout of the JR Propo servos listed, providing a straightforward way to replace cracked or worn housings. It helps preserve correct gear mesh and keeps the servo secured inside the scale drivetrain.

Designed for standard workshop work, fitment requires common hand tools and careful transfer of internal fixings. Inspect screw threads and posts for damage during the swap and confirm horn travel and end-stops before refitting in the model. The housing also helps reduce play that can degrade steering and throttle precision.
