Whether you’re running the legendary 5.9L 12v Cummins or the heavy-hauling 6.7L Cummins, our Workhorse Series is the ultimate defense against thermal stress, cracking, and dropped valve seats.

🔥 Is heat quietly killing your Cummins? 🛑

Most guys think valve reliefs are only for clearance. But here’s the real secret: It’s all about heat dissipation.

By adding valve reliefs to your Cummins head, you’re actually improving airflow right around the valve seat.

The Result? It pulls destructive heat away from the valves faster.

The Payoff? No more cracked heads or dropped seats when those EGTs start climbing. 📈

It’s not just about making room, it’s about protecting your engine. 💪

Why we throw away OEM 12v Cummins valve SEALS 🗑

Factory seals rely on a tiny band to grip the guide. Once that band loses tension, the seal loses its grip and starts traveling up and down with the valve, allowing oil to bypass the guide.

Our fix: Top Hat style Valve Seals

The base of this seal sits directly under the valve spring, physically pinning the seal in place. No more traveling seals, no more oil bypassing the guides.

👇 Have you found loose, traveling seals on your 12v teardowns?

At Choate, we’re obsessed with perfecting the process. That's why we torque plate hone. Using a torque plate mimics the stress of the cylinder head being installed. This ensures a perfect seal under real-world operating conditions, and ensures your engine's maximum life.

Don't settle for "good enough." Demand precision.

Don’t let a factory piston be the weak link in your build. 🛠️
When you’re chasing big horsepower, "standard" isn't enough. Our Choate Engineering Performance piston sets are engineered to handle the heat, literally.

✅️ Coated: For superior heat reflection and friction reduction.
✅️ Flycut: To provide the necessary clearance for high-lift cams.
✅️ Delipped: To eliminate the stress risers that lead to cracked pistons under pressure.

Precision machining meets heavy-duty durability. If you’re ready to build an engine that actually lasts, you’re ready for Choate.
