Differential Locker Spool, Aluminum, for TRA 8S 6S - Hot Racing

About this part

Aluminum diff locker spool for TRA 6S and 8S builds. Runs front, center and rear on the 8S and front and rear on the 6S. It puts the power where the grip is. With a regular center diff, power heads to the front tires as the truck accelerates. When those tires unload, they spin and you lose torque. The center spool replaces the diff action and sends torque to the tires that have traction, which means much harder acceleration than a center diff can deliver. The extra torque and stress hit the drivetrain hard, so this part is for off-road use only. The spool also works in the front or rear diff with the included aluminum diff cup mount rod.
