• 28cc dish design to optimize compression ratio and combustion chamber dynamics
• Premium piston rings included for enhanced sealing and reduced blow-by
• Designed specifically for the 6.1L HEMI SRT8 engine platform
• Heat-treated and stress-relieved to withstand extreme racing conditions
• Compatible with high-boost, nitrous, and forced induction applications
• Balanced for smooth operation and reduced engine vibration

Construction & Design

Wiseco Professional Series pistons are crafted from high-grade 2618 forged aluminum alloy, known for its exceptional strength and thermal stability under extreme conditions. The forging process enhances grain structure, providing superior fatigue resistance compared to cast pistons. Each piston undergoes precision CNC machining to ensure tight tolerances and consistent weight, critical for high-RPM reliability.

The 28cc dish design is engineered to optimize the combustion chamber shape, promoting efficient flame propagation and helping to control detonation in high-compression or forced induction setups. Additionally, the pistons are heat-treated and stress-relieved to minimize distortion and extend service life in demanding race environments.

Installation & Fitment

These pistons are direct replacements designed to fit the 6.1L SRT8 engines in the following vehicles: 2005–2010 Chrysler 300C, 2006–2010 Dodge Charger, 2006–2008 Dodge Magnum, 2006–2010 Jeep Grand Cherokee, and 2008–2010 Dodge Challenger. Installation requires standard engine rebuild procedures, including proper honing and cleaning of the cylinder bores. Due to their forged construction and precise dimensions, minimal modifications are necessary when installed by a qualified engine builder.
