Shopper Award

Weistec forged pistons and billet rods are designed as direct replacement for the OEM pistons and rods in the 6.0L V12 AMG engine. The pistons use a wrist pin that is stronger and of a better design that the oem pin.

The billet rods, which are of a stronger material and design than the original rods, are capable of supporting much higher power levels than the factory rods.

What Is Weistec Engineering?

Based out of Orange County, California, Weistec Engineering is an industry leader in research, development, and design.
