What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is selected for its superior strength and performance capabilities, making it suitable for demanding engine builds.

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

The cam and barrel (skirt) profiles on these pistons are engineered to generate substantial power while also being gentle on the cylinder walls. This design helps to reduce wear and maintain the integrity of your engine's cylinders.

Are piston rings and bearings included with this set?

This product listing is for the piston set only, which includes the pistons and wrist pins. Piston rings and connecting rod bearings are typically sold separately and should be chosen to match the specifications of these pistons and your engine build.

About this part

Product Details

Manley Performance is well-known for building strong engine components, and this piston set for the Toyota 5.7L 3UR-FE engine is a prime example. If you're rebuilding the top end of your 3UR-FE, these pistons are designed to handle the demands of performance builds. They feature a 94.65mm bore and a -24.00cc dish, which is a specific volume that affects compression ratio when paired with your cylinder heads and gasket thickness.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to perform under high stress. Manley also includes tool steel wrist pins, which are robust and reliable for performance applications. The skirt profiles are carefully shaped to generate power efficiently while minimizing wear on your cylinder walls. Plus, the ring lands and grooves are machined to very tight tolerances, which is crucial for achieving a good seal with your piston rings, leading to better compression and more power.

Manley's manufacturing process uses unique fixturing that allows them to machine the skirt and cut the ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, which further improves the ring seal. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings and bearings to match these pistons.
