MP11 Bevel Gear Upgrade 10T/20T - Kyosho IF715  [KY-IF715]

Bevel gear considerations for MP11 setup

The Kyosho IF715 Diff. Bevel Gear Set is supplied as a replacement gearing set for the Kyosho MP11 platform and preserves the 10T/20T tooth configuration shown in the original part code. The content below covers compatibility pointers, fitting approaches, and the way new bevel gears affect drivetrain feel during tuning sessions.

Compatibility and role: Specified for MP11 chassis fitment, this bevel set acts as a spare for worn or damaged rear diff bevels. Properly installed gears set the internal mesh geometry and influence backlash, torque transfer, and the overall responsiveness of the drivetrain during acceleration and load transitions.

Installation guidance: Inspect the diff carrier and mating surfaces, remove old grease and contaminants, and ensure the diff cross and side gears seat concentrically. Fit the 10T and 20T gears with smooth meshing and no binding, confirm free rotation across suspension travel, and re-check pinion alignment if the diff was stripped. Apply thread locking where the manual specifies and run-in gently under low load to validate engagement.

Tuning considerations: Replacing worn bevel gears restores consistent backlash and reduces slop from damaged teeth, which can enhance predictability on corner exit and improve traction control. Small changes in diff tightness, gear mesh, or shimming can noticeably alter drivability, so adjust incrementally and test in controlled conditions. Factor in bearing condition and diff oil choice when tuning the drivetrain.

For MP11 users, the IF715 set is an effective way to recover differential precision and support repeatable tuning outcomes.
