What is the bore size and compression height for these pistons?

These pistons have a bore size of 95.50 mm and a compression height of 34.30 mm. This specific sizing is critical for proper engine assembly and performance tuning.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating is applied to reduce friction between the piston skirt and the cylinder wall. This helps with quieter operation, improved lubrication, and resistance to seizure under high stress.

Are these pistons suitable for a stock engine rebuild?

These are Wiseco Professional Series forged racing pistons, designed for heavy to severe duty race builds. While they can be used in a performance-oriented rebuild, they are engineered for higher stress applications than a typical stock replacement.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for the demanding VR38DETT engine found in performance Nissan applications. The -7cc dome design is a specific choice for tuning compression ratios in high-performance builds, working in conjunction with the 95.50 mm bore size to achieve your desired engine output. These are not your average replacement pistons; they are designed for builders who push their engines hard.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and additional ring seal improvements. This attention to detail helps ensure a solid seal between the piston and cylinder wall, crucial for power and longevity under heavy loads. The pistons also feature forced pin oiling to keep the wrist pin lubricated, and an ArmorGlide skirt coating that helps reduce friction and noise while resisting seizure. The fully machined crown further ensures accuracy and consistency across the set of six.

If you're building a serious performance engine for racing or heavy-duty use, these Wiseco Professional Series pistons are a strong option. They are designed to withstand severe duty applications, offering a well-built foundation for your VR38DETT build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
