Diamond Introduces 2,000HP-Capable LS Race Series Pistons. The Most Powerful Shelf-Stock Pistons Ever!

November 2, 2017 / by Evan Perkins

Diamond's LS Race Series Pistons are the strongest shelf-stock pistons on the market, supporting a massive 2,000 horsepower. 

As the horsepower output of modern engines continues to spiral upwards, Diamond Pistons stands at the ready with the 2,000hp-capable LS Race Series pistons–an industry first in terms of horsepower capacity in a shelf-stock part. Having a stocking part of this capacity tremendously reduces the lead time for high-power LS street and race applications, which previously required a custom piston.

The fully strutted, forged, 2618 design features a reinforced crown and ring lands to maximize strength, 3D crown milling for exacting precison, and includes moly-coated-skirts to reduce friction. Born out of a two-year development program with a top, LS drag-race team, these pistons are ready to handle serious abuse out of the box, with no additional prep-work needed.
