• Coated skirts
• Tool steel nitrided rings with a napier second ring
• Upgraded forging capable of living at 1000+hp, the technology of this forging comes from existing Honda designs that make 1000+hp and survive!
• Offset pin .030 so you can run a tighter piston to wall clearance. For a "quieter" piston. (install with offset towards exhaust side)
• This LSJ piston design was developed in conjunction w/ GM for a secret project car. Will work with stock LSJ rods. 
• Made from a 2618 forging

We offer 3 options at this time:

• 2.0L/86mm in 9.5:1 compression which is stock.
• 2.4L/88mm in 10.4:1 compression which is stock.
• 2.1L/88mm in 9.6:1 compression (requires 2.0 rods/crank)

LSJ Note: These forged pistons will not work with the stock rectangular LSJ oil squirters. They must be replaced with the LNF/LDK tube type Gen 2 oil squirters. And, they need to be bent about .060" to the side to clear the JE pistons. 

Make sure to check oil squirter to piston clearance.
