The XRAY 333070 Belt Tensioner Set brings exacting belt adjustment to older NT series models. The kit contains a durable graphite plate and sturdy alloy bearing holders that help maintain correct belt tension for smoother drivetrain operation and reduced wear. Ball-bearings are not supplied, but the tensioner accepts standard bearing types for easy fitment into existing builds.
A practical replacement for hobbyists restoring or maintaining vintage XRAY NT cars, this tensioner improves belt stability and drivetrain consistency.
