A combined wheel nut indicator and dust cap, designed for wheels fitted with trims and step rings. The long reach barrel is built specifically for these wheel types, where a standard-length indicator wouldn't sit correctly.
Fitted in a consistent pattern – point to point is standard practice – the indicator gives an instant visual check: if a nut has worked loose, it's immediately obvious. It also melts at a set temperature, flagging potential brake or bearing overheating before it becomes a bigger problem. At the same time, it protects the wheel nut from water, road salt, dirt and general corrosion.
Available across a wide range of stud sizes (17mm–41mm) and colours – select your size and colour above. Sold as single units.
