Tired of playing the guessing game on what components to install in your engine to handle more power? Let us help! Our forged internal kits are a perfect way to stop worrying about what may or may not work. All packages come with AMTuned spec JE Pistons Package, Pauter Machine connecting rods with ARP hardware. AMTuned recommends this package to be used with Sleeved engine blocks, but they can also be used on the factory Alusil bores. Minimum bore spec is 3.3267" (84.5mm) for these pistons. We have tried various bore sizes on these in the 4.2 engines for mild to wild boost builds and have seen that you will start to notice cold start piston slap when surpassing 3.3285" bore size. AMTuned does not accept any liability for non in house engine builds. A professional engine builder is highly recommended.
Components Included:
- AMTuned Design JE Piston 9.5:1 CR, 2618 Alloy, 93 Series Pins, Gas Nitride Ring Package, Piston Skirt Coating
- Pauter Machine Connecting Rod's w/ ARP 2000 Hardware
