Exotek F104 Ultra diff axle & diff housing

Exotek Racing introduce two new option parts for the F104 series of formula cars in the form of an aluminium diff axle and diff housing. Starting with the diff axle, the combined 1-piece part reduces the play and weight of the stock axle with extra machining reducing the axle to only 4.5 grams whereas the stock part is 7grams. The axle is ideal for high speed conditions due to the lower rotating mass and reduced unsprung weight. Special machining makes for exacter diff ring tolerance to insure a better diff ring fit as the diff ring will not slip back and forth like in the stock diff.

The second new part is the extra lightweight axle differential housing for the F104 series of cars. Extra machining reduces the part’s weight to only 4.2 grams, saving around 1.5g of weight. Like the 1-piece diff axle the housing sports extra machining to ensure the best possible diff ring fit. Both parts are available polished and anodised in your choice of blue or black colour.
