MAHLE 197740100 PowerPak Forged Piston Kit 330ci 3.553in Bore 2618 Alloy

The MAHLE 197740100 PowerPak Forged Piston Kit is a complete, race-proven piston assembly engineered for serious engine builders and performance enthusiasts. Built from 2618 aluminum alloy, these pistons deliver exceptional detonation resistance and strength under extreme heat and cylinder pressure, making them ideal for high-output, forced-induction, and racing applications.

This kit is configured for a 330 cubic inch displacement build, featuring a 3.553-inch bore, 3.543-inch stroke, 5.930-inch rod length, and a 1.220-inch compression height. The -13cc dome volume (reverse dome / dished crown) is designed to achieve specific compression ratio targets. Each piston weighs just 364 grams and accepts a 0.866-inch wrist pin, balancing lightweight performance with structural integrity.

Key Features:

• 2618 Forged Aluminum Alloy — superior detonation resistance for forced induction and race engines
• Slipper Skirt Design — lightweight, low-drag forging for reduced reciprocating mass
• Grafal® Anti-Friction Skirt Coating — minimizes friction, reduces cylinder bore wear, and dampens piston noise
• Phosphate Coating — protects ring grooves and pin bores from micro-welding and galling during initial startup and break-in
• -13cc Dish Volume — engineered dome profile for precise compression ratio tuning
• 364g Piston Weight — optimized for balanced, high-revving applications
• 0.866-inch Wrist Pin — robust pin diameter for strength and durability
• Hand Deburred — precision-finished for consistent quality and fitment
