High performance extra lightweight axle differential housing for the F104 series of cars. Extra machining reduces the diff housing weight to only 3.6 grams (stock is 5 grams). Excellent for high speed conditions for lower rotating mass and reduced unsprung weight.
The reduced diff weight also helps remove tweak from the rear pod because the stock F104 rear pod is heavier on the right side.
Also machined for exacting diff ring tolerance to insure better diff ring fit. The diff ring will not slip back and forth like in the stock diff. Requires stock Tamiya hex diff rings 51347.
Polished and anodized in your choice of blue or black.
For F104 series of F1 cars (not F103 or F101).
