There are a lot of enthusiasts out there that are starting to push the limits of General Motors’ LS platform. What was once a wall at 1,000-horsepower, has now been shattered, and people are gaining ground on the 2,000-horsepower mark.

The problem is not the goal of making high power, it’s more about the parts needed to do so, and the ease of getting replacements. Sometimes, you will need ti have extra pistons on-hand, because what you need is a custom unit. You can’t just call a speed shop and order them. Instead, you will have to call the manufacturer, order the pistons, and then proceed to wait weeks for your order to ship.

Diamond Racing Pistons has a solution to this problem, and the final product is incredible. Their LS2K piston is a stocked item, so if you are in need of one piston or a set, they can ship it to you with no wait time. This super-tough custom piston is on the self and ready to go at a moments notice, which means less downtime for you and your race car.

The LS2K piston has exceptionally thick crown and ring lands for durability, and is designed to take some serious abuse. The oil ring has been pushed down into the pin bore to make the ring lands thicker. We talked to Evan Perkins of Race Winning Brands about this new piston. “We put the material where it is needed, and pulled it out where it wasn’t.” This piston has lateral gas ports, so whether it’s big boost you’re looking for or a healthy dose of N2O, this piston is sure to seal even with big combustion pressure. According to Evan, “This piston is one of the best parts we offer.”

The fit and finish of this piston are second to none, and everything was taken into consideration when the Diamond crew designed them. If you are in the market for a high-horsepower LS piston, we strongly suggest that you check out Diamond Racing Pistons for a complete look at the LS2K.
