Wiseco 4147GFX GFX Piston Ring Set Steel Nitrided Napier Style

The Wiseco 4147GFX is a high-performance GFX piston ring set designed for use with Wiseco pistons. This individual ring set fits one piston and is engineered around Wiseco's 1.2mm Steel Nitride and Napier GFX ring configuration — the same premium ring technology used across Wiseco's late-model EFI piston lineup and select small block Chevy applications.

Key Features:

• Steel Nitrided Top Ring — provides exceptional wear resistance and heat tolerance for high-performance and forced-induction applications
• Napier-Style 2nd Ring — improves oil control and sealing efficiency compared to standard taper-face rings
• 1.2mm GFX Ring Profile — thin ring package reduces friction and improves power output
• Individual Ring Set — fits one piston; order the quantity needed to match your cylinder count
• Compatible with Wiseco pistons designed around the GFX ring specification

The Wiseco GFX ring series represents a step above the Pro Tru plasma moly and NPR XX ring sets, offering superior material quality and tighter tolerances for demanding performance builds. Whether upgrading a street performance engine or building a dedicated racing application, the 4147GFX delivers the sealing performance and durability that Wiseco is known for.

Note: This ring set is sold individually and fits one piston. Order the specific quantity needed for your build.
