Tamiya TT-02 Aluminum Front/Rear Gearbox Cover and Upper Arm Stabilizer by GPM TT2012A  [TT2012A]

Aluminum gearbox cover and arm stabilizer

This GPM TT2012A aluminum upgrade replaces the front and rear gearbox covers and adds upper arm stabilizers for the Tamiya TT-02 platform. Made from machined 6061 T6 aluminum, the parts are intended for RC-scale use to improve bearing alignment and differential stability while helping dissipate heat from the gearbox.

The set includes the gearbox cover and an upper arm stabilizer for each end, plus the stainless steel fasteners needed for installation. Components are anodized and finished for corrosion resistance and consistent fit on the listed TT-02 variants.

Use this TT2012A aluminum set when you want a durable, OEM-fit replacement that tightens bearing clearances and serves as a passive heat sink for the gearbox; it suits hobbyists tuning driveline stability or those replacing worn plastic covers and upper arm mounts on applicable TT-02 variants.
