What makes these pistons suitable for severe duty applications?

These pistons are forged and machined from 2618 aluminum for improved tensile strength and feature a design engineered to withstand heavy to severe duty performance applications. They also include features like an anti-detonation groove and improved ring seal for added durability under stress.

What is the benefit of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these pistons helps reduce friction and noise during operation. It also provides seizure resistance, which is important for maintaining engine integrity under high loads.

Are these pistons compatible with all Ford Small Block 302 engines?

These pistons are designed for Ford Small Block 302 engines with a 4.040 inch bore. It is important to verify your engine's specific bore size and other dimensions against the piston specifications to ensure proper fitment.

Product Details

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for Ford Small Block 302 engines that demand serious durability. If you're building a race engine or a street/strip machine that will see heavy use, these pistons are designed to handle the stress.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength compared to cast aluminum. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, which is crucial for consistent power and engine health under high cylinder pressures. The fully machined crown ensures accuracy, and they also come with forced pin oiling to keep the wrist pins well-lubricated. Plus, they have an ArmorGlide skirt coating that helps reduce friction and noise while resisting seizure.

This set includes eight pistons, each with a 4.040-inch bore size, a 1.165-inch compression height, and a 0.927-inch pin diameter. They are designed for severe duty performance applications, meaning they're built to withstand the rigors of racing and heavy use. Please note that these pistons are not CARB approved and cannot be shipped to California.
