Racing Grade Gear Adaptor for Sakura Advance 20M

The 3Racing SAK-A551 - 7075 Aluminum Gear Adaptor for Sakura Advance 20M is engineered for competitive setups where accurate gear alignment and repeatable mesh are critical. Machined to tight tolerances from 7075 alloy, the adaptor reduces movement at the gear interface and supports consistent torque transfer under race conditions.

Technical Construction and Benefits

Fabricated from high-grade 7075 aluminium, the SAK-A551 provides a high modulus platform that resists deformation and preserves gear backlash settings. This stability aids in predictable drivetrain behaviour and reduces the need for frequent shimming during setup changes.

Fitment and Tuning Notes

Designed exclusively for the Sakura Advance 20M chassis layout, the adaptor installs directly and improves pinion to spur alignment. For optimal performance, verify centre distance and mesh under load, and use the adaptor as part of a systematic tuning routine to dial in acceleration and gear noise characteristics.

How should I set initial gear mesh for race trim?

Start with a thin paper method to establish contact, tighten to eliminate play, then run and recheck mesh after torqueing fasteners to spec to ensure stability under load.

Any recommendations for checking concentricity?

Inspect pinion and spur runout by rotating the assembly and feeling for wobble; a dial indicator is preferred when fine tolerances are required for competition.

Does the adaptor suit high torque brushless setups?

The 7075 construction handles increased loads better than softer alloys, but confirm gear tooth rating and shaft retention details when pairing with high torque motors.
