Carrillo MX1026-P Project X Pro Race Piston Kit 95mm 13.5:1 Profiled Pin Bore

The CP-Carrillo MX1026-P is a full-race, Project X Pro piston kit engineered for maximum performance and durability in high-compression powersports 450cc applications. The "-P" designation indicates CP-Carrillo's proprietary Profiled Pin Bore technology — an advanced process developed in partnership with high-end OEM companies that shapes the interior of the pin bore area to allow the wrist pin to flex naturally under load, dramatically reducing stress concentrations at one of the piston's most critical points.

Built from high-strength 2618 forged aluminum alloy, each piston in this kit is fully CNC-machined and balanced to within ±1 gram for exceptional smoothness at high RPM. CP-Carrillo's signature X-forging process minimizes mass without sacrificing structural integrity, while the fully boxed skirt design with skirt coating reduces friction and promotes long service life.

Key Features:

• Project X Pro Profiled Pin Bore: Proprietary pin bore shaping reduces stress in the most highly loaded area of the piston, increasing durability for serious racing programs
• 2618 Forged Aluminum Construction: High-strength alloy provides superior thermal resistance and fatigue life compared to cast alternatives
• Fully CNC-Machined & Balanced: Precision-balanced to ±1 gram for smooth, high-RPM operation
• Diamond-Like Coating (DLC) Wrist Pin: Harder than steel for unmatched pin durability and reduced friction
• Double Forced Pin Oilers: Delivers twice the lubrication from the cylinder wall to the wrist pin for enhanced longevity
• Radiused Dome: Maximizes quench area while eliminating hot spots that can promote detonation
• Accumulator Groove: V-shaped groove machined into the second ring land collects excess blowby between the top and second rings
• Gas-Nitrided Top Ring: Steel top ring with gas-nitrided facing for superior wear resistance
• 13.5:1 Compression Ratio: Race-spec compression for maximum power output
• 95mm Standard Bore: Direct standard-bore fitment, no boring required
