Are you looking to get the MOST out of your Gen III HEMI without worrying about failing internals? If you’re considering supercharging, turbo charging, running nitrous, or a combination of these then you have come to the right place. OK we have had great success with our drop in pistons for several years now so it is time to add the 5.7L HEMI platform to our lineup. These will match factory specs for balance and will not require any balancing(therefore no crank removal). We will be making the pistons from 2618 material and will include a premium ring package and tool steel wrist pins. For the rods in the package, we called on our good friend Tom Molnar of Molnar Technologies to design us a rod that would stand up to the new power levels and match factory weights. The ARP 2000 bolts used in all of our rods are of a proprietary design by Tom Molnar. 

No engine build delays - No balancing charges - Less down time - No engine shipping cost
