To go along with the new Mustang RTR Spec 5, Exotek Racing announces a new Alloy Diff Gear option for the HPI RS4 Sport 3 chassis. The new diff gear is designed to fit both the front and rear gearboxes of the RS4 Sport 3 and is machined from 7075 aluminum alloy to be lighter than the stock steel gear. It is also machined with tighter tolerance for a better bearing fit and smoother gear mesh, as well as being hard anodized for improved durability.
