K0112XS

Overview:

The Wiseco Professional Series forged pistons are engineered for serious racers and high-performance engine builders who demand uncompromising strength and durability. Designed specifically for the Chrysler 6.1L 3rd Generation HEMI V8 engine, this set of eight pistons offers a precision fit and advanced features to support heavy to severe duty race applications.

Whether you are building a track-only race engine or a high-output street machine, these pistons provide the reliability and performance needed to push your build beyond factory limits. Each piston is supplied with premium rings, ensuring optimal sealing and durability under extreme conditions.

Key Features:

Wiseco’s Professional Series pistons incorporate advanced design and manufacturing techniques to deliver superior performance and longevity:

• Forged from high-strength aluminum alloy for exceptional durability and resistance to thermal and mechanical stress.
• 5.5cc dome design to optimize combustion chamber volume and support increased compression ratios.
• 1.220 inch compression height tailored for precise piston-to-cylinder fitment in the 6.1L HEMI.
• 0.984 inch wrist pin diameter engineered for maximum strength and reduced reciprocating mass.
• Set of 8 pistons, perfect for complete V8 engine builds.
• Supplied with premium piston rings to ensure excellent sealing and wear resistance.
• Designed for heavy to severe duty race builds, capable of handling high boost, nitrous, and other extreme power adders.
• Precision CNC machining for consistent dimensions and reliable performance.

Construction & Design:

Each piston in this Professional Series set is forged using Wiseco’s proprietary forging process, which produces a dense, uniform grain structure for enhanced strength and fatigue resistance. The 5.5cc dome shape is carefully engineered to improve combustion efficiency and support higher compression ratios without sacrificing durability.

The pistons feature a robust pin bore sized at 0.984 inches to accommodate heavy-duty wrist pins, reducing the risk of failure under high RPM and load. The 1.220 inch compression height ensures proper deck clearance and ring positioning for optimal engine performance and longevity.

Installation & Fitment:

This piston set is designed as a direct replacement for the Chrysler 6.1L 3rd Gen HEMI engine, with bore size of 4.055 inches. The pistons fit precisely without the need for machining modifications beyond standard honing and clearance checks.

Installation requires standard engine assembly procedures. No special tuning or modifications are necessary to accommodate these pistons, but professional installation is recommended to ensure proper ring end gap and piston-to-wall clearance.

• Direct fit for Chrysler 6.1L 3rd Gen HEMI V8 engines
• No cutting, drilling, or special tuning required
• Compatible with high-performance race builds and heavy-duty applications
