The spool locks both wheels together, providing solid drive for improved traction and consistent power delivery on loose or uneven terrain.

What does a differential locker spool do?

A spool replaces the differential gears, locking the axle shafts together. This means both rear wheels spin at the same speed at all times. It is especially useful for drag racing, high-traction surfaces, or when you want to eliminate wheel spin from one wheel. Many RC enthusiasts use a spool to get maximum grip off the line.
