Kyosho IF715 Diff Bevel Gear Set for MP11 (10T/20T)  [KY-IF715]

MP11 bevel gear overview

The Kyosho IF715 Diff. Bevel Gear Set supplies replacement bevel gears intended for use with the Kyosho MP11 platform, maintaining the 10T/20T tooth pairing referenced in the part name. The text that follows highlights fitment guidance, installation points, and the practical effects fresh bevel gears have on drivetrain response during setup.

Compatibility and role: This bevel gear set is designated for MP11 chassis use and acts as a direct spare for damaged or worn rear differential bevels. In service these gears determine the meshing geometry inside the differential and thereby influence backlash, torque transfer traits, and how the drivetrain behaves under acceleration and deceleration in RC operation.

Installation guidance: Check mating faces and the differential carrier before installation, remove old grease, and ensure concentric seating on the diff cross and side gears. Install the 10T and 20T gears so teeth mesh without binding, confirm free rotation across suspension travel, and re-verify pinion alignment if you disassembled the diff. Use thread lock where called for in the chassis manual and perform a cautious run-in at low load to confirm engagement.

Tuning considerations: Replacing worn bevel gears restores consistent backlash and reduces play from damaged teeth, which can improve traction modulation and consistency out of corners. When altering diff preload or mesh, make small changes and test repeatedly on the same surface to evaluate effects. Also consider bearings and diff oil viscosity when tuning the drivetrain.

MP11 owners will find the IF715 set a direct way to return differential performance to a predictable baseline for setup and tuning.
