Yes they do drop directly in switching the inside bearing out. But just like the directions state for Tamiya cars to dremel some of the plastic off the steering knuckle for clearance. You have to do so with the HPI steering knuckles. BUT, you also have to slightly dremel a little of the C-Hub for clearance. I mean very little. If you don't dremel in both of these area's, The DCJ will hit. When installed it made the steering assembly way smoother. Hope this helps.
