The GPM MYT199F front main shaft uses precision aluminium styling and a Delrin wheel joint to strengthen the AXIAL YETI JR front driveline. Engineered to replace plastic originals, this component enhances torsional rigidity and improves power transfer consistency while reducing the risk of deformation under load. The unit retains a 99mm midpoint distance to match the Mini Yeti 1:18 JR setup and is aimed at serious hobbyists seeking a durable, performance oriented upgrade.
