Key Features:

• Forged 4032 Aluminum Alloy: All Wiseco pistons are forged from high-silicon, low-expansion aluminum for superior strength, reduced weight, improved heat transfer, and extended service life compared to cast alternatives
• Pro-Lite Series Construction: Lightweight dedicated forging and CNC diamond-turned finish minimize reciprocating mass for quicker throttle response and maximum torque output
• Precision CNC Machining: Computer-controlled turning centers ensure a consistent finish with no size variation, compatible with cast iron, chrome, Nikasil, and boron composite cylinder bore compositions
• Optimized Skirt & Dome Profile: Contoured piston design improves ring sealing, reduces cylinder wall friction, and maintains consistent compression
• Made in the USA: Engineered and manufactured at Wiseco's state-of-the-art facility for quality control at every stage of production
• Complete Kit: Includes forged piston, piston rings, taper-wall wrist pin (22mm), and circlips — everything needed for a full top-end rebuild
