What material are these Manley pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its strength and ability to perform well under high temperatures and pressures common in performance engines.

What is the purpose of the cam and barrel skirt profiles?

The cam and barrel (skirt) profiles on these pistons are designed to help them run smoothly and quietly within the cylinder. This design aims to generate substantial power while also minimizing wear on the cylinder walls over time.

Are these pistons compatible with all LS engines?

These pistons are specifically designed for Small Block Chevrolet LS engines with a 4.070-inch bore and a -29cc dish. While they fit a broad range of LS applications, it's always best to confirm your specific engine's bore size and desired compression ratio before purchasing.

About this part

Product Details

If you're rebuilding the heart of your Small Block Chevrolet LS engine, especially for a performance build where durability and power are key, these Manley pistons are a solid choice. They're designed to handle the demands of serious engine work, whether you're building a street machine or a track-focused powerplant. These pistons feature a -29cc dish and a 4.070-inch bore, making them suitable for a wide range of LS engine applications found in vehicles like the Chevrolet Camaro, Corvette, and Pontiac Firebird.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. This material choice is crucial for performance engines that see regular hard use. The pistons also feature proven cam and barrel skirt profiles, which help them run smoothly and quietly while minimizing wear on your cylinder walls. You'll also find exacting standards applied to the ring lands and grooves, which is essential for achieving a good seal with your piston rings, leading to more efficient combustion and better power output. The included chrome moly wrist pins are well-built and ready for action, ensuring reliable operation.

For those looking to push their LS engine even further, Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is a detail that professional engine builders pay close attention to for optimal ring seal and performance. These pistons are a significant upgrade over stock components and are built to last, making them a popular choice for engine builds that demand reliability and power.
