Traxxas 50K weight differential oil for the Revo but can be used in other vehicles.
INCLUDES: 1.75 oz (50cc) bottle of oil w/ 1-1/2 (38mm) pointed fill cap
Gave my rear axle more lock up than the stock oil. Works good
just what I needed fast shipping
I did the DIY sealed Traxxas diff mod, and this fluid seems to be staying in the diff and slowing the diff action perfectly; not too much, not too little.
