Kyosho EFW007-01 ball differential shaft for precise FANTOM EP drivetrains

If you run a Kyosho FANTOM EP, the EFW007-01 Ball Differential Shaft is a compact upgrade that tightens up your 4WD system. Machined from carbon and sized at 6mm, it balances low weight with the rigidity needed for spirited track sessions.

Built for strength and efficient power flow

The carbon 6mm construction of the Kyosho EFW007-01 delivers a lightweight yet sturdy shaft that reduces drivetrain losses. That translates to more consistent power to the wheels and predictable handling during acceleration and corner exits.

Designed to fit FANTOM EP systems

This shaft is matched to the FANTOM EP series geometry, so it installs without altering suspension or gearing geometry. The accurate tolerances keep the differential operating as intended and avoid unnecessary setup changes.

Simple install and care tips

Before fitting the EFW007-01, clean all mating parts and check for burrs or grime that could affect performance. Tightening to the correct torque and periodic inspections will help the shaft last through club nights and practice laps alike.
