Hot Racing Arrma Grom Aluminum Differential Locker Spool (Red)

The Hot Racing Arrma Grom Aluminum Differential Locker Spool Set is an optional upgrade for the Arrma Grom 1/18 Typhon, Mojave, and Granite platforms. It can be installed in either the front or rear differential to lock the wheels together, making them rotate at the same speed.

Designed for off-road use where equal power to the wheels on the same axle is needed, this spool is CNC machined from solid aluminum and features an anodized red finish with corrosion resistance. Recommended for low-traction off-road surfaces to help avoid driveline damage.
