Tamiya TRF420 steel front direct cup set
Coming from Tamiya and made for their TRF420 touring car is a steel front direct cup set. Designed as a stronger replacement for the standard lightweight aluminium front spool outdrives, the parts add durability and about 4g of weight, allowing to fine-tune the weight of the front and also the drivetrain’s behaviour under load. Included with the outdrives come four replacement driveshaft caps. In combination with the SP1642 TRF420 front direct pulley, the parts can also be used with the TRF419 and TA07 kits.
