What is the benefit of the ArmorGlide skirt coating?

The ArmorGlide coating on the piston skirts is designed to reduce operating friction and noise. It also helps to minimize wear on both the piston skirt and the cylinder wall, contributing to a longer service life.

Do these pistons come with wrist pins and rings?

Yes, each part number includes premium rings. The pistons also utilize a 0.927 inch pin diameter, and while wrist pins are typically included with performance pistons, it's always best to confirm the exact contents for your specific part number.

Why are these pistons not CARB approved?

These pistons are not approved by the California Air Resources Board (CARB) and therefore cannot be shipped to California. This is common for performance engine components that may not meet specific emissions standards.

Product Details

Forged from 2618 aluminum right here in the USA, these Wiseco RED series pistons are built for the demands of high-performance Chevrolet LS engines. The RED designation stands for Race Engineered Design, meaning they incorporate specific features to give you an edge, whether you're on the drag strip or the circle track. They're designed to handle the stresses of racing and power adder applications, offering a solid foundation for your engine build.

You'll find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pins and the small end of the connecting rods well-lubricated, crucial for making sure everything lasts. Wiseco uses dedicated forgings for these pistons, allowing them to create an optimized, strutted design that maximizes strength while keeping the weight down. Plus, each set comes with premium rings, so you don't have to hunt for those separately. The accumulator groove is another thoughtful touch, helping to maintain a consistent seal for the piston rings, which means more consistent power delivery.

These pistons are not approved for sale in California due to CARB regulations. If you're building a serious LS engine and need pistons that can take a beating and keep performing, this set from Wiseco is a well-built option.
