Tamiya 53390 - Carbon Gear Shafts for M03/M04 Chassis Race-Focused Hollow Shafts  [53390]

Performance-Focused Hollow Carbon Shafts

Made for Tamiya M03, M04 and FF02 platforms, the Tamiya 53390 Hollow Carbon Gear Shafts swap out heavier metal parts for stiff, lightweight carbon fiber to reduce rotating mass and improve on-track balance. The material choice maintains strength while lowering weight, helping handling and drivetrain efficiency during longer runs.

Smooth Power Transfer

These carbon gear shafts are designed to pass motor torque to the transmission with minimal inertia, producing a more responsive feel at the wheel. Their reduced weight supports quicker acceleration and crisper directional changes, useful whether you are refining lap times or enjoying club sessions.

Pack Contents

• One 20mm carbon gear shaft
• One 40mm carbon gear shaft

Bearing and Fit Details

For correct installation the shafts require eight 5x11mm bearings. These bearings pair with the shafts and transmission gears to support the idler, spur and counter gears inside the chassis. Each shaft measures 5mm outer diameter for a tight fit in the designated mounts.
