What is the compression height of these pistons?

The compression height for these Wiseco pistons is 1.278 inches. This measurement is critical for ensuring the piston sits at the correct level within the cylinder bore relative to the crankshaft centerline.

Can these pistons be shipped to California?

No, these pistons are not CARB approved and cannot be shipped to California. Please check local regulations for engine component compliance.

What does the -5cc dish volume mean for my engine?

The -5cc dish volume affects the engine's compression ratio. A dish volume generally lowers the compression ratio, which can be beneficial for forced induction applications or when using cylinder heads with a larger combustion chamber volume.
