The XRAY 355153 - 43T Active Center Differential Spur Gear is crafted for modelers who require accuracy and durability from their drivetrain parts. Manufactured from HUDY steel, this component is finished to deliver consistent, reliable engagement.
This 43-tooth gear is cut on specialist gear machines to preserve correct tooth form and alignment. The heat treatment process improves hardness and fatigue resistance, reducing deformation and wear during repeated running sessions.
Laser-etched with Active 43T, the gear is easy to identify during rebuilds or upgrades. Its sturdy build helps lower replacement frequency and keeps differential action smooth under load.
