Track-proven to 3,000 HP, Sonnax Extreme planetaries are the finest quality Powerglide planetary assemblies in the world. From carrier and output shaft to gears and thrust washers, every component is refined for maximum durability in the most demanding applications. The ring gears are even pre-drilled for the Sonnax stabilizer system to prevent vibration and broken reverse friction plates. Extreme gear sets feature Sonnax premium sun and pinion gears that also undergo the same advanced processing used in Formula 1, NASCAR® and other high-end professional racing circuits.
