How often should I service the ball diff?

Inspect the diff after heavy race days and clean or refresh grease every few race meetings. Ceramic balls and quality washers tolerate longer intervals but check for play and wear.

What oil or grease suits this diff?

Use a light diff grease for reduced stiction or a thin diff oil if you want quicker engagement. Test on your track to find the balance between traction and steering feel.

Can I adjust the diff during a race weekend?

Yes, the external adjustment screw allows trackside tuning. Make small changes and note handling differences to dial in the best setting for the surface.
