This titanium cap joint is an RC-scale replacement part intended for the Kyosho Inferno MP7.5 front and rear gearbox locations. Supplied as 2 pcs, the component serves as the interface between the driveshaft and the gearbox cap, intended to maintain alignment and transfer torque within the model drivetrain.
Installation is straightforward for anyone familiar with gearbox servicing: disassemble the gearbox cover, remove the original cap joint, fit the titanium piece in the correct orientation, and reassemble while checking gear mesh and bearing alignment. Use appropriate hex drivers and basic workshop care to avoid over-tightening fasteners.
In tuning terms this part is a targeted hop-up: it replaces a stock cap joint with a titanium unit that focuses on durability and consistent joint geometry in RC racing or club track setups. It is intended to support predictable drivetrain behaviour during setup changes rather than to alter suspension or motor characteristics.
