Revolution Design Racing Products have introduced new titanium pivot balls for the compatible to all 3rd generation of Team Associated RC8 kits including the RC8B, RC8B3e, RC8T3 and RC8T3e. Made from high-quality material the titanium pivot balls scrub a good amount of weight compared to the kit’s steel parts while also being much less prone to corrosion and wear, making them virtually a fit and forget. These titanium pivot balls are a direct replacement for the standard steel balls.
