    Sonnax offers complete Powerglide planetary assemblies available with a variety of gearset options. These assemblies come in various configurations to meet different build requirements. The output shaft is available in the OE length or short length and the machined from billet drum flange in 12-tooth (OE) or 24-tooth. It is common to find the sun gears showing wear and pitting well before pinion gears do.

    Extreme planetary assemblies include Advanced Process sun gears and pinions made to the same exacting standards used on Formula 1, Nascar and other high-end professional racing circuits.

    Advanced Process parts undergo an additional three-step process that allows for greater durability and higher levels of performance. These units are fully assembled and ready to install.

    • Cryogenic tempering to ultra-low temperatures (-350?F) for an even denser, more uniform gear with a tough and wear-resistant structure.
    • Shot peening for increased gear resistance to fatigue failure, cracking or galling.
    • Super-finish to reduce friction, vibration, noise and wear on the gear, potentially tripling the life of the part.

    Gear Sets

    Sonnax planetary gears are a big step up from standard case-hardened and tempered gears. Each gear set includes a flanged sun gear and a ring gear. The flange is machined from a billet, not a stamped piece. It is broached and matched to the sun gear for a precise press fit that does not require welding.

    Planetary Assemblies

    Planetary assemblies come in various configurations for different build requirements. The output shaft is available in the OE-length or short length and has a drum flange tooth profile which is 12-tooth (OE) or 24-tooth (fits Sonnax's 10-clutch drum). Units are fully assembled with a rear sun gear bearing upgrade and OE or steel-backed, PTFE-coated thrust washers.
