Choate High Performance Pistons

High Performance Choate Pistons

Polyphen Coated • De-lipped Bowls • Precision Flycut

Polyphen Coating

The Polyphen Coated Tops act as a thermal barrier to reduce heat transfer into the piston material. This reduction provides lower EGTs and lower oil temps.

De-lipped Fuel Bowl

Piston crowns are precisely machined to remove the sharp bowl lip. This corrects fuel spray trajectory and removes hot spots, significantly reducing the risk of cracking.

Flycut Valve Reliefs

Precision flycut valve reliefs eliminate piston-to-valve interference encountered when using performance cams, allowing for higher lift selection.

Technical FAQ

What is included in the piston set?

Every Choate Performance Piston Kit is a comprehensive set including ceramic-coated pistons, skirts, pins, locks, and a complete ring set.

What is the current lead time for machined sets?

To ensure precision, each set is machined specifically as ordered. Our current 1–3 week lead time allows for meticulous machining and quality control.

Are these pistons heavier than stock?

No, they are not heavier than stock. We meticulously manage the weight of every set to ensure they remain within OEM specifications.

Do these pistons work with stock connecting rods?

Yes, they absolutely do. Our pistons are engineered as high-performance, drop-in replacements that are fully compatible with your factory OEM connecting rods.

Do I need to balance my rotating assembly?

While it is not strictly required, we highly recommend balancing your rotating assembly as a best practice for any high-performance engine build.
