Powerglide Pump Stator - HEAT-TREATED - 4140 - OEM STYLE

ATI Racing’s OEM-style pump stator, crafted from heat‑treated 4140 alloy steel, serves as a direct-replacement component designed to precisely center and lock the stator assembly inside the torque converter under load. Built to OEM form and fit standards, this high-strength stator tube resists torsional stress during torque multiplication, preventing stator rotation and preserving proper converter function. It also provides a trusted surface for input shaft oil rings, enabling accurate fluid sealing and proper routing of oil through the pump and cooler circuits. Manufactured to ATI’s exacting specifications in the USA, this stator delivers durable hydraulic integrity, improved cooler flow, and enhanced longevity in high-performance or race‑level transmission builds.
