One of Diamond Pistons‘ newest products for the LT engine is no exception to the brand’s reputation. The new GM Gen V L83 pistons are machined from forged, 2618 aluminum, and are designed for nitrous, boost, and extremely high-horsepower applications.

The L83 pistons are available in an abundance of compression heights and support longer stroke crankshafts, making the L83’s a perfect choice for your high-horsepower LT application.
