SpeedTek RC Arrma 6S Locked Differential Spool W/O Diff Cups (Front, Center Or Rear). Also compatible with the Arrma Limitless, Infraction and Felony Models too.
 
Fits all three differentials (Front, Center and Rear). Replaces differential components (ARAC4010) completely locking it up.
 
Locking differential forces both left and right wheels on the same axle to rotate at the same speed under nearly all circumstances, without regard to tractional differences seen at either wheel. A locked differential can provide a significant traction advantage over an open differential, but only when the traction under each wheel differs significantly. IDEAL for on road no-prep drag racing and speed runs applications. Rated up to 8S LIPO.*
