Regular price $4,195.95

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 JE Pistons, AMTuned Saenz manufactured connecting rods, ARP 2000 connecting rod bolts, and connecting rod bearings. AMTuned recommends this package to be used with Sleeved engine blocks, but they can also be used on the factory Alusil bores. A properly prepped stock bore care will have the bores trued for out of roundness, and re prepared utilizing the appropriate Alusil honing techniques. A professional engine builder is highly recommended.

AMTuned has released our new H beam connecting rod manufactured by Saenz Performance. They are created with the latest FEA technology to ensure strength and reduce weight. We have designed these connecting rods and piston package to handle 1,800HP! (225HP per piston/rod) spinning at over 8krpm. We know it will be a bit of time to see if anyone can actually achieve those numbers on this platform, but wanted to make sure our components are up for the challenge.
