• ArmorGlide® skirt coating — reduces operating friction and noise, minimizes wear on skirt and cylinder walls, and allows tighter piston-to-wall clearances
• Fully machined crown with precision ring grooves and anti-detonation groove (ADG) for improved durability under boost or nitrous
• Precision-fit wrist pin included — 0.927 in. diameter floating pin design for reliable, low-friction operation

Wiseco has manufactured performance forged pistons in the USA for over 80 years, drawing on experience from Formula 1, NHRA Pro Stock, and other elite motorsports programs. The K0422X185 is the ideal foundation for a high-compression or forced-induction Chevy LS stroker build demanding uncompromising strength and precision.
