Wiseco K397X100 Forged Piston Kit Chevy LS 4.100 in. Bore -32cc Dish Stroker

The Wiseco K397X100 is a Professional Series forged piston kit engineered for high-performance Chevrolet LS stroker builds. Designed around a 4.100 in. bore and optimized for a 4.000 in. stroke with a 6.125 in. rod length, this shelf-stock kit delivers race-proven reliability straight off the shelf for serious engine builders.

Featuring a -32cc dish crown, this kit is purpose-built for stroker LS applications where controlled compression ratios and combustion efficiency are critical. The 0.927 in. wrist pin diameter and dedicated LS-specific forging geometry ensure precise fitment and optimal strength-to-weight balance.

Key Features:

• Forged from 2618 aluminum in the USA for superior tensile strength in racing and power-adder applications
• -32cc dish volume for optimized compression tuning in stroker LS builds
• 4.100 in. bore with 4.000 in. stroke and 6.125 in. rod length compatibility
• 0.927 in. wrist pin diameter with dedicated forging for engine-specific structural integrity
• ArmorGlide® skirt coating reduces operating friction and noise while minimizing skirt and cylinder wear
• Precision-machined ring grooves for consistent ring seal and long service life
• Designed for heavy-duty to severe-duty race applications including high-boost and nitrous builds
• Kit includes 8 forged pistons and a premium ring set
