What is the benefit of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these Wiseco pistons helps to reduce friction between the piston skirt and the cylinder wall. This leads to quieter operation and improved resistance to seizure, which is beneficial for demanding engine builds.

Are these pistons suitable for a stock engine rebuild?

These Wiseco pistons are designed for heavy to severe duty race builds and performance applications. While they can be used in a performance-oriented rebuild, they are not typically intended for a standard, stock replacement scenario due to their advanced features and intended use.

What does 'flat top no VPs' mean for installation?

A 'flat top' piston means the top surface of the piston is level, without any valve reliefs (VPs) or dish. This design is crucial for achieving a specific compression ratio, especially in performance builds where precise deck height and combustion chamber volume are critical.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in your Volkswagen Type 1 engine. The 94.00 mm bore size is a common upgrade for air-cooled Type 1 engines, offering a solid increase in displacement. This set is designed for flat-top applications, meaning they are flush with the cylinder deck when installed, which is crucial for achieving the correct compression ratio in many performance builds. The pistons also feature precision ring grooves, anti-detonation grooves, and additional features to improve ring seal, all contributing to better combustion efficiency and durability under stress.

Wiseco has applied an ArmorGlide skirt coating to these pistons. This coating helps reduce friction between the piston skirt and cylinder wall, leading to quieter operation and improved seizure resistance, especially important in high-performance or heavy-duty applications. The crown of each piston is fully machined, and they incorporate forced pin oiling to ensure the wrist pins stay well-lubricated. These pistons are intended for demanding builds where reliability and performance are paramount.

This kit includes four pistons, ready to be installed in your Volkswagen Beetle, Fastback, Squareback, or Transporter. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
