Wiseco Ford Small Block 302 4.040in Bore 1.090in CH -7.50 CC Piston Set

If you're building a high-performance Ford Small Block 302 and need pistons that can handle serious abuse, this set from Wiseco is a solid choice. These are their Professional Series forged pistons, designed from the ground up for heavy-duty racing applications where reliability is just as important as power. They're built to take a beating, whether you're on the track or pushing your engine hard on the street.

Wiseco makes these pistons in the USA from 2618 aluminum, which gives them improved tensile strength compared to cast aluminum. That means they can better withstand the extreme pressures and temperatures found in a performance engine. You'll also find precision ring grooves, anti-detonation grooves, and features designed to improve ring seal, all contributing to better combustion efficiency and durability. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated under high load. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and quiet down operation.

This set includes eight pistons, each with a 4.040-inch bore size, a 1.090-inch compression height, and a 0.927-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For any serious Small Block 302 build, these Wiseco pistons are a well-built foundation.
