STATOR SUPPORT TUBE, HEAT TREATED (W/ BUSHING FOR TURBO SHAFT)

The Coan Racing COA‑12809 Stator Support Tube is a precision-engineered replacement component designed to reinforce the rear of the front pump assembly in GM Powerglide transmissions equipped with turbo-style input shafts. Machined from heat-treated steel, the tube restores structural rigidity and hydraulic alignment in the pump-to-stator area, while the integrated bushing supports the turbo spline shaft to minimize endplay and reduce wear.

This tube installs directly into the transmission case, eliminating pump misalignment and enhancing durability under high-torque conditions, making it an essential upgrade for both performance builds and rebuild restorations.
