More About D.S.S. Racing

For more than 30 years, D.S.S. Racing has produced the highest quality pistons available. 10,000 D.S.S. powered engines and counting.

The D.S.S. core concept has always been to produce a high value product that will provide superior quality and performance. Through the years we have honed our manufacturing skills. Today we manufacture an innovative line of pistons that are forged and machined at our Saint Charles IL. facility. These forged pistons are used in thousands of racing cars, street cars and hot rods, including many record setting and championship efforts.

D.S.S. Racing E Series Pistons

D.S.S. Racing's E Series Pistons provide quality, well-made pistons at affordable prices that compete with low-quality imports. Being on a budget no longer means sacrificing quality. The E Series easily outperforms and outlasts poorly made cheap imported pistons. The E Series has all the assets of a forged piston at a cast price.

D.S.S. Racing SX Series Pistons

The SX Series Racing Pistons take a step up in features and build quality. SX Pistons are Blower, Turbo and NOS ready and have CNC machined valve reliefs for moderate performance heads and cam combinations. If you feel like it's time to take a step forward and still stay within your budget, the SX Series is exactly what you're looking for.

D.S.S. Racing GSX Series Pistons

Leap into the world of high performance pistons with D.S.S. Racing's GSX Series. Great care has been taken to reduce the piston weight by adding CNC milling in non-critical areas, and even larger and deeper CNC valve reliefs allow more aggressive cylinder head and cam combinations.All GSX Series pistons have the patented 'X Groove' skirt as a standard feature. The groundbreaking X-shaped groove sweeps excess fuel and foreign matter in the oil drainback holes on the downstroke and into the side relief on the upstroke. This sweeping effect keeps the debris from getting trapped between the piston skirt and the cylinder wall, where it would normally cause scoring damage. With exoct fuels, blowers, Turbos and NOS running at today's power levels, ultra rich mixtures are required and commonplace. The X Groove combats the damaging effects of these applications, improves ring seal, cylinder wall condition and piston skirt condition. The X Groove is a major breakthrough in the racing world.

D.S.S. Racing XR Series Pistons

The XR Piston Series is the ultimate expression of precision piston making. Why? Because it's painstakingly made for your precise application. You become the collaborator with us in creating your XR pistons. Your engine specs, your fuel, your desired compression, alloy, ring width and placement...everything about the XR is custom. if you're building an engine that has special needs, then the XR Series can meet all of thos needs, and at a price that's probably lower than you would expect. Our XR pistons are as customizable and well-made as any pistons in the racing world today.
