The FMS FCX10 11001 Differential Locker (C3239) is a genuine OEM replacement differential locker for the FMS 1:10 FCX10 RC crawler. Locking the differential forces both wheels on an axle to rotate at the same speed, maximising traction when one wheel loses grip — an essential feature for technical off-road crawling. This replacement part restores full locker functionality to the FCX10 axle.
Direct OEM fit for the FCX10 11001 axle. Backed by a 90-day warranty.
