Description

The Sonnax Smart-Tech big input shaft kit 22121B-08K is an extreme-duty, 1-1/8” diameter 35-spline input shaft. It features a .100” larger diameter at the sealing ring cross-hole area and is a one-piece shaft forged from ultra-high strength 300M billet steel, eliminating weak connections. It maintains OE oil flow areas and eliminates leakage for predictable, trouble-free lockup, release, and apply. A custom stator assembly optimizes performance and long-term durability.
