ARIAS PISTONS are forged from billet 2618 (non-silicon) or 4032 (12.5% silicon) billet aluminum, depending on the application. Pistons forged from billet raw material offer ultimate tensile strength and fatigue resistance, and retain a true 100% wrought (extruded) structure throughout. Don’t confuse “powerforged” or “budget” forged pistons with ARIAS premium billet forged pistons!

ARIAS PISTONS feature:
• Hi-tensile forged, not cast, billet material
• Proper forging cross-sections
• CNC machined working surfaces
• Micro-flat Sure Seal ring grooves
• Optimized crowns for efficient combustion
• Diamond-turned ellipsoidal skirt profile
• Ultra close no-rock skirt clearance
• Consistent measurements part-to-part

ARIAS kits include:
• Forged pistons.
• Wrist pins: high carbon, case-hardened.
• Locks: carbon steel wire or spiral.

High quality matching chrome / nitride steel or moly faced ductile iron ring sets are available separately. We also have Total Seal ring sets in Zero-Gap and standard gap designs.
