About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Performance Piston Set is a solid choice. These pistons are designed for a 4.185-inch bore and feature a -20.00cc dish, making them suitable for various performance applications where specific compression ratios are needed. Manley has been a go-to for serious engine builders for a long time, and this set reflects that experience.

What sets these pistons apart is the material and the machining. They're forged from domestic 2618 alloy, which is known for its strength and ability to handle high temperatures and pressures without deforming. Manley also uses proven cam and barrel skirt profiles. This design helps the piston move smoothly in the cylinder, reducing friction and wear on your cylinder walls while still allowing the engine to make good power. The ring lands and grooves are machined to very tight tolerances, which is crucial for getting a good seal with your piston rings. A good ring seal means better compression, less blow-by, and ultimately, more power from your engine.

This set includes premium chrome moly wrist pins, which are strong enough for many performance builds. For those pushing the limits even further, Manley offers upgraded wrist pin options in stronger alloys. Manley's unique manufacturing process allows them to machine the skirt and cut the ring grooves in one operation, ensuring the grooves are perfectly square to the piston skirt. This attention to detail is what separates a good engine build from a great one. Keep in mind these are not CARB approved and cannot be shipped to California.
