New Two-Piece TH400 Forward Drum

New Two-Piece TH400 Forward Drum


The new two-piece TH400 forward drum eliminates the common issue of seal wear often found in full aluminum drums that have been in the market for years. This upgrade includes 8620 steel center that prevents seal wear and overpowering the center splines in big horsepower applications, a Vasco 300 shaft, and 7075-T6 aluminum housing with hard anodized coating reducing weight causing less horsepower drag in the drive train—increasing your transmission’s overall life. 

This extremely durable piece is suitable for all drag racing transmissions, especially those looking to optimize performance. We’re currently offering the two-piece TH400 forward drum in the 30 spline version (Turbo) for now as we look into its modular design more to create larger shafts in the future. The shaft and drum come finished and ready to install your piston and clutches. 

So what are you waiting for? Get the new two-piece TH400 forward drum that combines the strength of the steel shaft and the center hub’s weight savings of the aluminum clutch drum housing. Get it here.
