Suncoast Converters 1.80 Ratio Extreme Planetary Assembly Kit - No Shaft 28180G-NS

Sonnax offers complete GM Powerglide planetary assemblies in a variety of gear set options and configurations. Track-proven to 3,000 HP, Sonnax Extreme planetaries are the finest quality Powerglide planetary assemblies in the world. Every component is refined for maximum durability in the most demanding applications. The ring gears are pre-drilled for the Sonnax stabilizer system, 28510-S3, to prevent vibration and broken reverse friction plates. Extreme gear sets feature Sonnax premium sun and pinion gears that undergo advanced processing used in Formula 1™, NASCAR® and other high-end professional racing circuits. This kit is compatible with all Sonnax extreme duty input shafts, although it's primarily for use when building a big input shaft system. Includes all the same parts found in complete Sonnax 1.69 assembly kits, minus the output shaft, rear sun gear and washer that must be purchased separately when building a big shaft system. Features top-quality sun and pinion gears, a 24-tooth billet drum flange designed to work exclusively with Sonnax clutch drums, and a bolt-together carrier for ease of service.
