    LQ9 replacement forged piston help

    Well, after searching various manufacturer website, and all the ls1 related sites, ive yet to get the info to be able to choose a piston i'm in need of.

    Simply put, i need a set of forged pistons that will fit a factory bore with stock lq9 rods and crank.

    ot really a tall order i'm thinking, but after 3 days, i still have yet to find a part number, anyone able to point me in the right direction maybe?

    Would appreciate it alot.

    Contact a Mahle distributor, they are OEM suppliers for the GenIII engine and manufacture forged pistons in addition to the hyperutechnics.
