Product Details

These precision-machined pistons feature a -6.83cc dish volume and are designed to work with all 23-degree cylinder heads.

Key Specifications:

  • Bore Size: 4.040 inches

  • Rod Length: 6.000 inches
  • Compression Ratio: 9.8:1 (with 64cc combustion chamber)

Carrillo pistons are manufactured from high-grade forged aluminum alloy, providing exceptional strength and durability for high-performance and racing applications.

These pistons are ideal for street performance builds, bracket racing, and engine rebuilds where reliability and consistent performance are critical.

Found all parts in stock and fair prices overall great

Very easy to order parts.

Very easy to use! I liked being able to search by car year, make and model!

Fast, Good website, however we will see if this obsolete part is actually available

very smooth sailing, thanks

Fast thats all i gotta say

Great pricing. (Check on google and they were the cheapest and had great reviews.) Quick shipment and everything is as they said it would be.

It was very fast and easy to get around. Good Job with you site.

I found my part easily (vent visors), checkout was simple, and I was notified the very next day that my item has been sent. The price (including shipping) was way lower than anywhere else online or in town.
