ARRMA ARA311227 Dogbone 40.5mm (2pcs)

The ARRMA ARA311227 Dogbone Set (40.5mm) is a genuine replacement drivetrain component designed to keep your RC vehicle running smoothly and reliably. These dogbones transfer power from the differential to the wheels, making them a critical part of your drivetrain system.

Each set includes two 40.5mm steel dogbones, precision-manufactured for a secure fit with differential outdrives and consistent performance. Built from strong steel, they are designed to withstand the stress of high-speed driving and rough terrain.

Commonly used in ARRMA Grom and NASCAR small-scale platforms, these dogbones are ideal for replacing worn or bent shafts to restore proper power delivery and drivetrain efficiency.
