Description

 

BILLET ALUMINUM FWD/DIR PISTON (.750") W/ CHECKBALL

 

The Coan Racing COA‑22830B billet aluminum forward/direct piston is a high-performance enhancement crafted to strengthen the front clutch pack of Turbo Hydramatic 400 transmissions. Machined from premium billet aluminum in the USA, this 0.750″-tall piston increases hydraulic volume and improves structural rigidity compared to standard cast units. This version has a built-in checkball feature, which ensures precise fluid control and reliable clutch engagement under pressure, particularly during aggressive launches and high-heat conditions.

 

It installs as a direct replacement, requiring no case or drum modifications, delivering enhanced sealing and engagement consistency crucial for drag, bracket, or street/strip builds that demand front-end durability and repeatable performance.
