- Made from Imported Japanese SAE 4140 Steel
Crafted from high-quality SAE 4140 steel sourced from Japan, known for its excellent strength and durability. SAE 4140 is an alloy steel with chromium and molybdenum, providing high fatigue strength and wear resistance, making it ideal for high-performance automotive applications. - Forged, Double Tempered, and Super Sub-Zero Treated for Unsurpassed Toughness
Each flywheel undergoes a meticulous manufacturing process, starting with forging to enhance its structural integrity. The flywheels are then double tempered, a heat treatment process that further strengthens the steel, and super sub-zero treated, where they are cooled to ultra-low temperatures to increase toughness and resistance to stress fractures. - Proprietary Nitride Surface Treatment for Increased Surface Hardness
To maximize durability, the flywheels are treated with a proprietary Nitride surface treatment. This process infuses nitrogen into the surface layer, creating a hard, wear-resistant exterior that can withstand high friction, increasing the flywheel's lifespan and reliability under extreme conditions.
