Owners of the Kyosho FANTOM EP will find the EFW007-01 Ball Differential Shaft a handy upgrade to refine 4WD balance. The 6mm carbon build keeps mass down while resisting flex under load.
The carbon material in the Kyosho EFW007-01 reduces rotating mass without sacrificing durability, helping the drivetrain respond more quickly and keeping handling consistent lap after lap.
Made to fit FANTOM EP components, this shaft integrates with the original differential layout and avoids the need for geometry changes, so you can install and get back on the circuit fast.
When fitting the EFW007-01, wipe mating surfaces clean and verify alignment before final tightening. Periodic checks for play or damage will preserve the shaft's performance over many running sessions.
