Axial Differential Gear Set

If you want to use the Wraith as a rock racer this is a must have in my opinion. Not so much as crawler but even then you could opt to use the gears and fill the diff with 150.000 wt diff oil and still have some limited slip action in the diff.
So much tighter steering and stability at speeds

agree with other reviewr. i used these in a wraith i converted to 4ws, worked perfectly. i just left them open with grease
smooth and turns on a dime on any surface.
