Wiseco K393X100 Piston Set Chevy LS Series -25cc Shelf Stock Kit

The Wiseco K393X100 is a shelf-stock piston set designed for Chevrolet LS Series engines, featuring a -25cc dish volume for optimized compression ratios in naturally aspirated and forced-induction builds. Wiseco shelf stock kits offer enthusiasts and engine builders a ready-to-ship solution without the lead times of a custom forged order.

Wiseco pistons are manufactured from forged 2618 aluminum alloy, providing exceptional strength and thermal expansion characteristics suited for high-performance and racing applications. The forging process creates a denser, stronger piston compared to cast alternatives, making these ideal for boosted, nitrous, or high-RPM LS builds.

Key Features:

• Forged 2618 aluminum alloy construction for superior strength and durability
• -25cc dish piston design for controlled compression ratios
• Compatible with Chevrolet LS Series engine family
• Shelf stock availability for faster delivery compared to custom orders
• CNC-machined to tight tolerances for consistent ring seal and reduced blow-by
• Designed for use with Wiseco rings and wrist pins (included in kit)
• Skirt coated for reduced friction and improved wear resistance

The Wiseco K393X100 shelf stock piston kit is an excellent choice for LS engine rebuilds and performance upgrades where a proven, off-the-shelf forged piston solution is needed. Each set is manufactured to Wiseco's exacting quality standards and is ready for professional or enthusiast installation.
