TRF420 Alu. F Direct Cups, spare parts, aluminum

The TRF420 Alu. F Direct Cups set is a focused spare parts release for the front drivetrain of the TRF420 chassis. With 2 aluminum front direct cups and 1 swing shaft cap parts set in the pack, it provides the named replacement parts needed when wear begins to affect the front drive section and running efficiency starts to drop. The direct cups are made from lightweight aluminum and finished with a hard coating. That combination gives the parts a low-mass construction at a point in the drivetrain where repeated contact matters, while the coated surface is specified to support durability during regular use. The shape is designed for the TRF420 chassis, so the set suits planned maintenance as well as like-for-like replacement during a rebuild of the front end. Compatibility also extends to cars using the TRF420 Front Direct Pulley 37T, which broadens fitment within TRF420-based setups. On the bench, this set fits naturally into routine drivetrain servicing, especially when worn cups begin to influence how cleanly the front section transfers drive. It also makes sense as a workshop spare for race-day maintenance, where having the correct front-end hardware ready can shorten downtime between running sessions.
