930276047

Overview:

The Mahle Piston Set is engineered for high-performance applications, specifically designed for 350 cubic inch displacement stroker builds featuring a 5.7L HEMI platform. This piston kit is ideal for enthusiasts and professional builders seeking reliable, precision-fit components that enhance engine durability and efficiency. Compatible with all 5.7L and 6.1L HEMI cylinder heads, this set supports a range of performance upgrades and rebuilds.

With a dome design optimized for a 10.9:1 compression ratio, these pistons deliver a balance of power and reliability, making them suitable for street performance, racing, and stroker engine configurations. The kit’s specifications ensure proper fitment and performance in stroked 5.7L HEMI engines, providing a solid foundation for increased displacement and power output.

Key Features:

Mahle’s piston set combines advanced engineering with high-quality materials to meet the demands of performance engine builds. Key features include:

• Precision-machined 3.947-inch bore diameter and 1.205-inch compression height for accurate fitment
• 3.579-inch stroke and 6.242-inch connecting rod length optimized for 350cid stroker applications
• 0.927-inch wrist pin diameter for robust piston-to-rod connection
• 10.2cc dome volume supporting a 10.9:1 compression ratio for enhanced combustion efficiency
• Lightweight design at approximately 448 grams per piston to reduce reciprocating mass
• Manufactured from 2618 aluminum alloy, known for excellent strength and thermal resistance
• Dome piston shape tailored for HEMI combustion chambers to maximize power and reduce detonation risk
• Compatible with all 5.7L and 6.1L HEMI cylinder heads, ensuring versatile application

Construction & Design:

Mahle pistons are crafted from premium 2618 aluminum alloy, a material favored in high-performance engines for its superior strength and ability to withstand elevated temperatures and pressures. The alloy’s durability ensures long-lasting performance even under demanding conditions such as high RPM and boost.

The dome design is specifically engineered to complement the hemispherical combustion chambers of 5.7L and 6.1L HEMI engines, optimizing flame travel and combustion efficiency. Precision machining guarantees tight tolerances for excellent ring sealing and minimal blow-by, contributing to improved power output and engine longevity.

Installation & Fitment:

This piston set is designed for direct fitment in 350cid stroker builds using 5.7L HEMI blocks. Installation requires standard engine assembly procedures, including proper ring orientation, wrist pin installation, and torque specifications. Due to the dome volume and compression ratio, it is recommended to verify piston-to-valve clearance and deck height during assembly.

Compatible with all factory 5.7L and 6.1L HEMI cylinder heads, this kit offers flexibility for builders upgrading or rebuilding these engines without the need for extensive modifications.

What's Included:

• Set of four Mahle forged pistons (3.947" bore diameter)
• Wrist pins sized at 0.927 inches
• Compression rings and oil rings (if applicable, verify with seller)
• Installation instructions and technical specifications

Ideal For:

This Mahle piston set is ideal for automotive enthusiasts, engine builders, and professional racers who are constructing or upgrading 350cid stroker engines based on the 5.7L HEMI platform. It suits applications ranging from street performance to competitive motorsports where reliability, strength, and precise fitment are critical.
