The 3Racing grey gear set SAK-D651/GY matches the Sakura D6 Sport chassis with precise M1.2 x 14 x 34mm sizing and an 11.5T tooth profile. Supplied as a two-piece set, it aims to restore correct engagement and reduce drivetrain inconsistencies caused by worn gears.
Check gear mesh at all mounting points and use a light film of suitable lubricant on contact faces. Regular inspection after race days will reveal any early signs of wear so you can swap parts before reliability is affected.
