How durable is the B9-501MCSA for regular track use?

The steel construction is intended to resist wear under typical racing loads, but you should inspect the part regularly for signs of wear or deformation after hard sessions.

Will this fit earlier BD9 versions?

This part is specified for BD9 2019 and compatible Yokomo models. Check your chassis dimensions and service manual to confirm fit before installation.

What maintenance does the spool need?

Keep the splines and contact surfaces clean and inspect for scoring or flats. Replace the cup if excessive wear appears to avoid drivetrain damage.
