hpi WR8 Center Diff Semilock proto

This part replaces one of the large gears inside the center diff.

 

I use this part to lock the front outdrive to the center diff. It makes the car much more stable and easier to control, it undesteers a bit on throttle, and it brakes always more in the front. Combine it with 200k-500k diff oil, where 200k will give you a more or less fwd car and 500k is more like a completely locked diff.

 

It features two M3 holes where you can put two screws to pull it out from the diffcase if you need to.
