Input Shaft Cup (Safe-D) (ARA311144)

Input Shaft Cup with Safe-D is a durable replacement part for ARRMA vehicles, designed to restore reliable drive in Safe-D-equipped drivetrains when the original cup wears or fails.

Machined from strong steel, this Safe-D input cup is built to withstand demanding RC use and is designed to pair with Safe-D compatible input gears matched to the main differential gear. The Safe-D design keeps the input gear and drive cup engaged, helping maintain drive even if the securing screw loosens. The package includes one input shaft cup and an M4 x 6mm set screw for secure installation.
