Carrillo Piston Features:

• Double Pin Oilers (opposed to single pin oilers), in conjunction with our annular reservoir, can add twice the amount of oil fromthe cylinder wall to the wristpin bore. This is a standard option on any piston that receives forced pin oiling.
• Lateral gas ports are horizontal slots in the top of the top ring groove and they provide a passage for combustion pressure to get behind and above the top ring, increasing ring seal with reduced radial
  rings. Lateral gasports are often used over the vertical option when carbon build up (which could clog vertical gasports) may be an issue.
• Vertical holes from the deck of the piston to the back of the top ring groove which allow combustion pressure to directly enter the top ring groove area for maximum ring seal. When not under load, the ring has
  normal tension for reduced friction.These are most commonly used for drag race applications.
• Broaches are horizontal slots in the pin bore designed to allow oil to enter between the wristpin and pinbore. Broaches are also used to accommodate the wristpin shape under compression, as it can be come somewhat oval and needs room in order to alleviate galling.
