Not directly. You will need to bore out the outer pin hole on the c-hub from 2mm to 2.5mm to accommodate the larger HB pin size. You will also need to shim the c-hub in the arm with a couple 0.5mm shims or it will float front to back.
The HB steering knuckle is taller so you will need to file it down about 0.5mm for it to fit into the c-hub.
The yokomo king pin collars are a different size too. May want to pick up a few packs. #BD-414C
I use the BD8 -1mm hubs on my car. They have more room for the DCJ's. But either Yokomo hub is way more durable than the stock HB.
Hope this helps. Good luck.
