Manley Small Block Chevy LS Series 4.135in Bore - 1.065in CD Extreme Duty Platinum Series Pistons

When you're building a high-performance Small Block Chevy LS engine, the pistons are a critical component that needs to handle serious stress. Manley's Extreme Duty Platinum Series pistons are built for just that, using a strong 2618 alloy forging that's known for its durability under demanding conditions. These aren't just off-the-shelf parts; they're designed with proven cam and barrel skirt profiles to help generate power efficiently while also being kind to your cylinder walls during operation.

What sets these pistons apart is the attention to detail in their construction. Manley uses domestic 2618 alloy forgings for their strength and includes premium chrome moly wrist pins as standard, with options for even tougher alloys like 9310 or Turbo Tuff/DLC on select part numbers for added longevity. They also hold their ring lands and grooves to strict standards, which is key for getting a good seal and maximizing the power your engine makes. The unique fixturing Manley employs allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other for optimal performance.

If you're aiming for serious power and reliability in your LS build, these pistons are a solid choice. They come ready with tool steel wrist pins and moly skirt coatings on this specific part number, offering a well-built package for serious engine builders. Keep in mind these are not CARB approved and cannot be shipped to California.
