What is the purpose of the -24.00cc dish in these pistons?

The -24.00cc dish is a design feature that helps reduce the compression ratio. This is often used in modified engines where higher boost pressures or different cylinder heads might otherwise lead to excessive compression, helping to prevent detonation.

What type of wrist pins are included with this piston set?

This specific Manley piston set includes premium chrome moly wrist pins. Manley also offers upgrades to 9310 and Turbo Tuff/DLC alloys for even greater durability in select part numbers.

Are these pistons coated on the skirts?

The manufacturer description mentions moly skirt coatings on select part numbers. While this specific set is built with proven skirt profiles, it's best to confirm if a moly coating is applied to this particular SKU if it's a critical feature for your build.

About this part

Product Details

Starting with domestic 2618 alloy forgings, these Manley pistons are built for serious performance in your Toyota 5.7L 3UR-FE engine. This set is designed for a 94.00mm bore and features a -24.00cc dish, which is a notable design choice for managing compression ratios in modified engines. Professional engine builders and tuners often turn to Manley for their reliability and the power gains these pistons can help achieve.

Manley pays close attention to the details that make a difference. The pistons feature proven cam and barrel skirt profiles, which help them run smoothly against the cylinder walls while still generating substantial power. They also use exacting standards for the ring lands and grooves, ensuring a tight seal for improved combustion efficiency. Each set comes with premium chrome moly wrist pins, and for certain applications, upgrades to even more durable alloys are available, though this specific set includes the standard chrome moly pins.

The unique fixturing Manley uses allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves are perfectly square to the skirt, which is critical for optimal ring seal and overall engine performance. If you're rebuilding the top end of your 3UR-FE and looking for a well-built, durable set of pistons that can handle increased demands, this Manley set is a solid option.
