Wiseco Toyota Tacoma 2RZ 3RZ Dished -10cc Piston Shelf Stock

Wiseco is well-known for making strong internal engine components, especially for performance builds. This particular piston, part number 6642M95, is a great example of their commitment to durability. It's designed for Toyota's 2RZ and 3RZ engines, commonly found in the 1995-2004 Tacoma, as well as the 4Runner and T100 models from the mid-90s to early 2000s. If you're rebuilding your engine for heavy use or demanding applications, these pistons are built to handle the stress.

These pistons are forged from 2618 aluminum right here in the USA, which gives them improved tensile strength over cast aluminum. They feature a dished crown with a -10cc volume, precision ring grooves, and anti-detonation grooves to help seal better and prevent issues under high pressure. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The crown is fully machined, and the design includes forced pin oiling for better lubrication.

Because these are built for severe duty, they're a solid option if you're pushing your engine hard. Keep in mind that these are not CARB approved and cannot be shipped to California. You'll want to check the manufacturer's instructions for any specific installation requirements, especially regarding ring gap and assembly.
