JE Pistons Small Block Ford (20 Degree Head) 4.030 Bore / 1.600 CD / -5.00 CC - Set of 8

If you're building a high-performance Small Block Ford engine, these JE Pistons SRP Pro 2618 pistons are a solid choice. They're designed for a 4.030 inch bore and feature a -5.00cc dish, which is important for setting your compression ratio correctly. The 1.600 inch compression distance (CD) also plays a key role in piston-to-valve clearance and compression height.

These pistons are forged from 2618 aluminum, a strong material that's well-suited for demanding performance applications. JE Pistons uses a proprietary Forged Side Relief (FSR) design that helps reduce friction and skirt wear, while also saving weight. The ring groove placement is proven to maintain a good seal, even in boosted or high-horsepower builds, and the top land is thick for added strength. An accumulator groove is included to help reduce combustion gas pressure, which further improves ring seal and keeps power consistent. Plus, they come with gas-nitrided carbon steel rings, wrist pins, and locks, all made 100% in the USA.

This set includes eight pistons, rings, wrist pins, and locks, so you have everything needed to get started on your engine build. Keep in mind these are not CARB approved and cannot be shipped to California. For serious performance builds, these JE Pistons offer a well-built foundation.
