Wiseco Performance Products — American Forging Power & Extreme Durability

### Brand Heritage & The Forged Advantage Founded in 1941 by motorcycle racer Clyde Wiseman in his Cleveland, Ohio garage, Wiseco Performance Products is the world's most renowned manufacturer of high-performance forged pistons, crankshafts, and clutch components. For over eight decades, Wiseco has remained the benchmark for American manufacturing excellence, engineering components that conquer the most demanding motorsport environments from AMA Supercross and Lucas Oil Pro Motocross to GNCC and Baja 1000 desert racing.

Operating from a massive 150,000 square-foot manufacturing facility in Mentor, Ohio, Wiseco is one of the few piston manufacturers in the world that controls the entire production process under one roof. Wiseco operates its own forging presses, tool-and-die shops, CNC machining centers, and surface coating lines. This total vertical integration allows Wiseco engineers to optimize grain flow, eliminate microscopic porosity, and produce components with structural ductility and impact toughness that cast components cannot match.

• Racer Elite Forged Pistons: Flagship CNC-machined 2618 aerospace alloy pistons featuring boxed-bridge architecture, ArmorGlide skirt coatings, and DLC-coated wrist pins.
• Complete Bottom-End Rebuild Kits: Precision-forged crankshafts, double-honed connecting rods, Japanese Koyo main bearings, and complete bottom-end gasket/seal kits.
• Forged Performance Clutch Baskets: Teflon-impregnated hard-anodized forged aluminum clutch baskets that eliminate plate tang notching.
• Pro-Lite 2-Stroke & 4-Stroke Piston Kits: Lightweight forged pistons engineered for instantaneous engine spool-up and maximum fatigue life.
• Complete Engine Rebuild Packages (Garage Buddy Kits): Comprehensive all-in-one engine kits containing crankshaft, piston, gaskets, hour meter, and hardware.

### How Wiseco Forgings Outperform Cast OEM Components 1. Ductile Grain Alignment: Casting molten aluminum into molds creates random crystalline structures with microscopic air pockets that fracture under extreme shock. Wiseco hot-forges raw aerospace billet aluminum under thousands of tons of hydraulic pressure, compressing the alloy and aligning the grain structure along the stress axes of the piston for unmatched strength. 2. ArmorGlide & DLC Technologies: Wiseco's proprietary ArmorGlide skirt coating reduces friction and bore wear, while their Diamond-Like Carbon (DLC) coated wrist pins eliminate small-end pin galling under extreme high-RPM racing temperatures. 3. Forged Clutch Baskets: Mass-production cast clutch baskets quickly develop jagged notches on the tang fingers from plate impact. Wiseco forged baskets are hard-anodized and Teflon-coated, eliminating tang wear for hundreds of operating hours.

### In-House Forging Metallurgy & Engineering Wiseco utilizes aerospace-grade 2618 and 4032 aluminum alloys, custom-alloyed to precise metallurgical specifications. The forging process compresses the aluminum billet into a high-density preform that eliminates void spaces, resulting in pistons that withstand combustion chamber pressures exceeding 1,500 PSI and operating speeds over 14,000 RPM.

• Crankshaft Assembly: Always use a dedicated crank puller tool to draw the crankshaft into the engine cases. Never strike a crankshaft with a hammer or mallet, which ruins factory trueing.
• Piston Clearance: Always verify piston-to-cylinder clearance using a micrometer and dial bore gauge according to the enclosed Wiseco spec sheet.
• Clutch Hardware: When riveting or bolting the primary drive gear to the Wiseco clutch basket, use high-strength red thread locker and torque to 12-14 Nm.
• Piston Ring Installation: Verify that the engraved manufacturer marks on the piston rings face upward toward the cylinder head before sliding the cylinder down.
