Hey guys have one set left of standard bore Wiseco EJ257 Piston ready to ship!

These pistons are rated for over 700HP on the EJ257 (supporting mods of course). These pistons are significantly lighter than the factory Hyper-cast pistons (thus reducing stresses on the overall rotating assembly), and of course significantly stronger.

The Wiseco pistons have tighter tolerances then most aftermarket pistons, which reduces piston rock, and are thus perfectly suitable for street use.

$499 Shipped!!!!

Installation Available!!



Thanks,

Gary
