These are 92 grams lighter than the OEM pistons (Almost 25% lighter than factory pistons, which is huge!), and are compatible with either the Mopar OEM Connecting Rods or the K1 Technologies H-Beam Connecting Rods (see photos).

Included with these pistons are JE Pro Seal piston rings, wrist pins, and wrist pin locks.

Does the .020 overbore compensate for the removal of the stock cylinder sleeves to fill the space?

  You should not be removing the stock sleeves. If you go to an overbore piston, you will have a local machine shop bore out the stock sleeve.

  Yes, you can bore out your engine block and use 20 thousandths over pistons without sleeves. Going larger than 20 thousandths and you'd need to get sleeves though.

  JE does not specify a horsepower level, but this type of forged piston can easily handle 600-700 horsepower, maybe even more.
