These new kits will come in 3 configurations, a 411, 422, and 426 cubic inch based on the 6.2L HEMI block. We chose to package these particular configurations based on performance and reliability. Our 411, 422, and 426 Hellcat stroker kits use a 2.100 rod journal as opposed to a 2.000. This provides additional material in a critical are for strength which is known as overlap between main and rod journals. The strokes used for 411, 422, and 426 allow for additional rod length to be used which reduces loading on piston and block and also increase piston dwell time for added power. If you would like to discuss this in further detail feel free to contact Dave Weber.  

Since 2005 Modern Muscle Performance has been innovating in the Gen3 HEMI with great success based on a legacy of racing knowledge from Dave Weber. We are not a rush to market platform. We research and apply our experience to every part we offer. Don’t settle for anything less than the absolute best when it comes to protecting your investment, your pride and joy, your HEMI powered hotrod!
