CR Piston Ring Set 4.440 Bore File Fit

The CR Piston Ring Set 4.440 Bore File Fit from Total Seal is designed for serious engine builders and mechanics who require precision in high-performance and rebuilt applications. This file-fit ring set is specifically made for a 4.440-inch bore diameter, making it ideal for stroker builds and competition engines where exact bore sizing is essential.

Total Seal's reputation for superior compression ring technology ensures that this set is a trusted choice for professionals. File-fit rings require precision honing and final bore sizing to achieve the correct end-gap clearance, allowing the rings to expand naturally during engine operation without binding or excessive blowby. The CR ring design optimizes oil control and compression retention, reducing friction losses and maximizing power transfer.

Engine builders, machine shops, and performance mechanics will find this ring set beneficial when working with bores already sized to 4.440 inches or when honing a block to that specification. This product is particularly suited for small-block and mid-displacement platforms, ensuring that users can achieve championship-caliber engine performance.
