This is the same sun gear included with Sonnax Smart-Tech® direct drum and shaft kit 76656-01K that combines high-strength direct drum with integrated intermediate stub shaft.

Unique sun gear is precision-machined from 9310, heat-treated steel
Can be used with stock-size shaft and drums for medium-duty or budget builds
