What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these Wiseco pistons is designed to reduce friction between the piston and cylinder wall. This also helps to minimize noise during operation and provides resistance against seizure, contributing to the overall longevity of the engine.

Are these pistons suitable for a street-driven car or only for racing?

These Wiseco Professional Series pistons are specifically designed and built for heavy to severe duty race builds. While they can be used in a high-performance street application, their construction and features are optimized for the extreme demands of racing.

What is the compression height and pin diameter of these pistons?

These pistons have a compression height of 1.050 inches and a pin diameter of 0.927 inches. This information is crucial for calculating the final compression ratio when paired with specific connecting rods and crankshafts.

These pistons are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding builds. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The fully machined crown and forced pin oiling are also notable details that contribute to their performance and longevity. Plus, they come with an ArmorGlide skirt coating that helps reduce friction and noise, while also resisting seizure.

This kit includes a set of 8 pistons, each with a -11cc dome, a 4.030-inch bore, a 1.050-inch compression height, and a 0.927-inch pin diameter. They are designed to fit a range of LS-based engines, including those found in the 1997-2004 Chevrolet Corvette, 1998-2002 Chevrolet Camaro, and 1998-2002 Pontiac Firebird, as well as the 2004 Pontiac GTO. Please note that these pistons are not CARB approved and cannot be shipped to California.
