The Dynamic Racing TH-400 Reverse Manual Valve Body is perfect for street/strip, drag racing or off road when total control of the shifts is necessary.
We start with a seasoned cast iron GM core, then we thermally clean it, machine it for reverse pattern function then assemble.
It is then put on our in-house dyno for complete testing to ensure full function.
Each kit includes:
- The modified valvebody
- modulator plug
- New separator plate
- New Direct drum springs
- Complete Instructions
Kit does not come with the stock manual valve. Reuse your existing valve or contact us to purchase a reconditioned one.
