Precision Hastings 3.900 Bore File Fit Rings

For engine builders demanding absolute precision, this Hastings File Fit Piston Ring Set is the gold standard. Engineered for a 3.900-inch bore, these rings allow for custom gap tuning to match your specific engine build requirements. The gas-nitride stainless steel construction ensures that once the gap is set, the rings maintain their integrity under the intense pressures of high-performance racing.

Key Features and Specs:

  • Bore Size: 3.900 inches
  • Gap Type: File Fit for custom clearance
  • Dimensions: 1.2 x 1.2 x 3.0mm
  • Material: Gas-nitride stainless steel
  • Application: 8-Cylinder high-performance builds

The 1.2mm ring profile significantly reduces friction compared to traditional ring sets, contributing to improved throttle response and overall engine efficiency. Because these are file-fit rings, they provide the flexibility needed for forced induction or high-compression naturally aspirated setups. Hastings is renowned for their exceptional quality control, ensuring that every ring in the set meets the highest standards for circularity and tension. Achieve the perfect seal for your custom engine build with high-quality components from GGCRACING.
