Performance MID topdeck for BD9

The Arrowmax AM-910021 AM Medius MID Topdeck is a 2.0mm Hard Type 2 replacement part built for the Yokomo BD9 MID chassis. Mounted in the MID position, it alters chassis torsional stiffness to help refine handling characteristics.

This topdeck is intended for on-track tuning: increasing rigidity through the MID region to affect steering response and chassis balance under cornering. It is a direct-fit hop-up for BD9 MID setups and should be used as part of a measured tuning program rather than a single quick fix.

Installation notes: the unit replaces the MID section and uses existing BD9 MID mounting points compatible with the original AM Medius topdeck. No extra hardware is listed; reuse your chassis fasteners and observe the manufacturer's torque recommendations.

Specifications

  • Item: AM Medius Yokomo BD9 MID Topdeck Type 2
  • Material: Hard Type 2
  • Model Number: AM-910021
  • Compatibility: Yokomo BD9 MID

Choose this topdeck when you want a firmer MID section to tune handling; adjust shocks and anti-roll balance incrementally to judge effects on entry and mid-corner performance.

How should I start setup after fitting this topdeck?

Begin with your baseline setup and make one change at a time, such as slightly softer rear shock damping or reduced rear anti-roll to rebalance after stiffening the MID.

Does the AM-910021 affect chassis flex tuning?

Yes. The AM-910021 adjusts torsional flex in the MID region, so it should be considered alongside other flex parts when tuning handling feel.

Is paint or finish likely to chip during install?

Handle the part carefully and avoid overtightening fasteners. Use correct torque values to prevent stress marks around screw holes.

Will this topdeck work with aftermarket brace kits?

It will work with many aftermarket bracing options if they are designed for the BD9 MID layout; confirm mounting compatibility before combining parts.

Any special maintenance after fitting?

Check fastener torque after a few runs and inspect for new stress points; re-torque as needed to the chassis manufacturer's spec.
