930276037

Overview:

The Mahle Piston Set is engineered for high-performance applications, specifically designed for 349 cubic inch displacement stroker builds based on the 5.7L HEMI platform. This piston kit features a dome design optimized for compatibility with all 5.7L and 6.1L HEMI cylinder heads, making it an excellent choice for enthusiasts looking to upgrade or rebuild their engines with reliable, precision components.

Ideal for builders seeking to increase displacement and compression ratio, this piston set delivers a 10.9:1 compression ratio with a 10.2cc dome volume, supporting enhanced combustion efficiency and power output. The kit is well-suited for stroker engine configurations, offering durability and performance consistency under demanding conditions.

Key Features:

Mahle’s piston set incorporates advanced engineering and materials to ensure optimal performance and longevity. Key features include:

• Precision-machined 3.937-inch bore diameter with 1.205-inch compression height
• 3.579-inch stroke and 6.242-inch connecting rod length for a 349cid stroker setup
• Lightweight design at 445 grams per piston to reduce reciprocating mass
• 0.927-inch wrist pin diameter for enhanced strength and stability
• 10.2cc dome volume to achieve a 10.9:1 compression ratio, optimized for performance
• Compatibility with all 5.7L and 6.1L HEMI cylinder heads for versatile application
• Manufactured from 2618 aluminum alloy, known for excellent fatigue resistance and thermal conductivity
• Dome piston design tailored for stroker engines to improve combustion chamber dynamics

Construction & Design:

Crafted from premium 2618 aluminum alloy, these pistons offer superior strength and durability required for high-performance and stroker engine applications. The 2618 alloy is favored for its excellent fatigue resistance and ability to withstand elevated temperatures, making it ideal for racing and heavy-duty use.

The dome shape of the piston is engineered to optimize combustion efficiency and support the increased compression ratio of 10.9:1. Precision machining ensures tight tolerances for a perfect fit within the cylinder bore, while the lightweight design minimizes reciprocating mass, contributing to improved engine responsiveness and reduced wear on connecting rods and crankshaft components.

Installation & Fitment:

This piston set is designed for direct compatibility with all 5.7L and 6.1L HEMI cylinder heads, simplifying installation in stroker engine builds based on these platforms. While professional installation is recommended, the pistons fit standard bore sizes and stroke configurations associated with 349cid stroker kits.

Builders should verify clearances and ring end gaps during assembly to ensure optimal performance and longevity. The kit is ideal for engine rebuilds or performance upgrades where increased displacement and compression are desired without extensive modifications to the cylinder heads.

What's Included:

• Set of Mahle pistons sized for 349cid stroker build
• Wrist pins compatible with 0.927-inch diameter
• Installation guidelines and specifications

Ideal For:

This Mahle piston set is perfect for automotive enthusiasts, engine builders, and performance shops focused on upgrading or rebuilding 5.7L and 6.1L HEMI engines. It suits applications ranging from street performance to racing, where increased displacement and compression ratios are required to extract more power and efficiency from the engine platform.
