The XRAY 333070 Belt Tensioner Set helps restore proper belt tension on vintage NT series models. It includes a precision graphite plate matched with alloy bearing holders to stabilise belt routing and reduce slop in the drivetrain. Ball-bearings must be sourced separately, but the design is compatible with common bearing sizes used in RC cars.
A sensible upgrade for enthusiasts maintaining classic XRAY NT vehicles, the set enhances drivetrain reliability during club runs and practice sessions.
