Project X Pro Technology:

CP-Carrillo's Project X Pro pistons utilize an advanced pin bore treatment process developed through years of collaboration with high-end OE manufacturers. Instead of traditional honing, specialized machines create specific shapes and forms inside the pin bore area that allow the piston pin to flex naturally while dramatically reducing stress concentrations. This proprietary process significantly increases piston durability by addressing one of the most highly stressed areas in any piston design.
