Wheel Nut Indicators

Our wheel nuts are torqued to manufacturer specifications, and are then fitted with high-visibility wheel nut indicators. The indicators are fitted in a uniform pattern, so when a wheel nut has loosened, the indicator will become out of sequence. The wheel nut indicators are also heat sensitive. If there is a binding brake or seized bearing, the heat is transferred through the stud and nut. If this temperature exceeds 120º C (248º F), the indicator will start to blister around the circumference and eventually start to distort. Pre-flight walkaround checks now can include wheel nut checks.

LED Lighting & Electrical

LED sealed beam wiring system with stop / turn/ tail lights recessed in a structural tubing bumper to meet FMVSS 108 ensure long life of these signaling lights.  Automotive-grade wiring harness features SAE bullet-style connectors at each light, ensure easy replaceability of individual lights.  SAE 7-way socket protected top sides and back with almag housing.  Sealed breakaway with charging circuit and LED battery condition indicator with 450 C.C.A. maintenance-free battery.  Recessed ABS license plate housing with integrated lamp provide very high protection of both the license plate and its illumination.
