Premium-Quality Forged Pistons
DSS FX-Series forged 4032 alloy pistons will withstand the demands of today's high-performance naturally aspirated, nitrous, or boosted engines. These premium aircraft-quality 4032 alloy pistons are forged and machined to perfection with internal gussets that provide added strength. Additionally, CNC milling removes non-critical material, resulting in a lighter weight and perfect balance of power, strength, and longevity. The DSS FX-Series piston patented X-Groove skirt design reduces damage caused by fuel washdown and break-in debris for superior skirt, cylinder, and ring life. This advanced skirt design is ideal in stroker engines and will improve piston stability and ring seal, resulting in quieter operation. Choose the pistons that best suit your application needs and push the limits of your engine combination.
