Show original supplier description
The MMX 6.1L HEMI Forged 2618 Drop-In Pistons and Rods Power Package is engineered for enthusiasts seeking to maximize their Gen III HEMI engine's potential without compromising internal component integrity. This package is designed to support up to 1000 RWHP, with some users achieving up to 1300 RWHP with additional supporting modifications. It is ideal for those planning to enhance their engine with supercharging, turbocharging, or nitrous systems. The package includes MAHLE Modern Muscle 2618 forged pistons, which match factory weight for balance, eliminating the need for crank balancing and reducing installation time. These pistons feature a moved-down top ring, an accumulator groove between rings, a Napier oil control second ring, a steel top ring, coated skirts, and coated ring lands. Molnar or Manley connecting rods, which also match factory weight, are included and feature custom ARP 2000 bolts for enhanced strength. Optional coated bearings are available for high horsepower builds, and the compression ratio ranges from 9.7 to 10.0:1 depending on gasket selection. Professional installation and clearance confirmation are required for this power package. The manufacturer advises checking local and state laws for emissions compliance before purchasing. Optional accessories such as a ring filer, ring compressor tools, and various gasket options (including Cometic 5-layer head gaskets) are available, as are different bearing options to suit specific build requirements.
