    The value-priced Contender series features high-quality Powerglide planetary assemblies which offer a significant upgrade from OE helical gears. Rated up to 1,000 horsepower, Contender series come assembled with Sonnax Premium 9310 sun gears, 8620 pinion gears, OE-style thrust washers and OE length, 4340 cut-spline output shafts or short length, HY-Tuf shafts. The billet drum flange is a 12-tooth (OE) design. The gears in Contender series gear sets are covered by a one-year warranty.

    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.
