JConcepts - 4mm large flange serrated locknut - 4pc

Fits - B5/B6/B6.1, Traxxas, TLR, Serpent, Kyosho, Xray


JConcepts has your 4mm wheel nut needs covered with the large flange serrated wheel nut set.   These high precision wheel nuts are designed with a large flanged area for additional support against the wheel and serrated for locking security.    The large flange and clamping surface area supports the wheel and helps maintain geometry during flex and load.   The larger area also provides more footing for the serrated area which provides a more comfortable lock-down.   The JConcepts wheel nuts are light-weight and intended for use on the RC10B5, RC10B5M along with most Traxxas vehicles.    The 4mm wheel nut is quickly becoming a new industry standard in 1/10th vehicles and securing the wheel gives that all important peace of mind.
