Precision Steering Upgrade for MP9 with IFW459D

The Kyosho IFW459D Servo Saver Assembly is a precision upgrade for MP9 owners seeking tighter steering and added servo protection. The hard spring provides a firmer centre that helps keep inputs accurate on demanding layouts.

Specifically for the Inferno MP9 Line

Crafted to match the Inferno MP9 mounting and geometry, this servo saver suits racing and high-performance setups. Its durable components help absorb shocks and limit stress transmitted to the servo.

Performance Benefits of a Hard Spring

A hard spring reduces free play and improves centring behaviour, which is useful for drivers aiming for consistent lap times and predictable handling. Combine with a low-backlash servo for best responsiveness.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Does the IFW459D need special tools to fit?

Fitting the IFW459D does not require special tools beyond standard hobby screwdrivers and pliers, though care is needed to centre the servo and secure linkages correctly.

Will this saver help prevent servo gear damage?

By absorbing sudden impacts and reducing direct shock to the servo, the IFW459D can lower the likelihood of gear damage when installed and used properly.

Can I use this with a digital racing servo?

Yes, the IFW459D works well with modern digital servos; pairing it with a high-torque, precise unit will maximise steering accuracy and consistency.

Does the hard spring affect tyre wear or handling balance?

The firmer centring can change how the car returns mid-corner, which may require small setup tweaks. It does not directly increase tyre wear but can alter how inputs are applied, so monitor handling and adjust setup as needed.

Are replacement parts available for the saver?

Spare parts for the servo saver are typically available through Kyosho dealers; check part numbers and source genuine components for reliable replacements.
