TH400 Extension Housing
Suit OEM & Super Hydra 400 Transmission With Bushing

The Reid Racing Turbo 400 tailhousings are stronger and more rigid than a stock GM tailhousing due to our use of aircraft grade aluminum alloy, thicker walls, and additional gusseting. Precision machining and perfectly aligned bores minimize power loss while maximizing reliability. Our reworked oil passage improves lubrication for the yoke and rear bushing. Fit all stock GM Turbo 400 transmission cases as well as Reid Racing's Super Hydra 400 transmission case.
