When racing a TH400, it’s critical to upgrade the forward and direct drums. The key is not only stronger, more durable parts, but improving efficiency for better performance, consistency and safety.
Grab a radical edge over the competition with the game-changing Sonnax Smart-Tech drum module! It’s the first and only TH400 upgrade to optimize drum function with a unique configuration of both lighter and stronger components.
The result: a big boost in transmission efficiency for more power to the ground, traction/stability on the shifts and the best protection you can get against catastrophic drum failure.
This all-in-one kit delivers a great value: it includes all-new, top-quality components for upgrading the forward/direct drums and everything else from intermediate sprag to back of the pump.
