TH400 Drum Dyno Demo: OE vs. Sonnax Smart-Tech Drum Module

Presented by Sonnax

When racing a GM TH400, it’s critical to upgrade the forward and direct drums. The key is not only stronger, more durable parts, but improving transmission efficiency for better performance, consistency and safety. This video gives you a closeup look at drum operation during a live dyno test. It's a unique demonstration of the OE design flaws and how the Sonnax Smart-Tech^® drum module 34555-01K optimizes performance with a revolutionary configuration of both lighter and stronger components.
