The Kyosho EFW007 6mm Ball Differential Set upgrades the driveline on FANTOM EP cars for crisper turn-in and steadier exits. Its carbon shaft balances strength with lower mass to aid responsiveness.
The carbon shaft resists twisting under load, delivering more precise torque transfer and better predictability when powering out of corners on track or around the street course.
Designed for plug-and-play replacement in the FANTOM EP range, the set lets you upgrade without modifying the gearbox or chassis layout.
With robust construction, the EFW007 helps keep lap times consistent and reduces the frequency of diff rebuilds for regular club use.
