BBTV 5570 Engine Piston Ring

Overview

This engine piston ring is built for 4-cylinder applications with a standard 4.000-inch bore and a deep oil groove design. Part number 5570 is listed for a wide range of classic Buick, Chevrolet, Oldsmobile, Pontiac, American Motors, and Jeep applications.

It uses grey iron for the top and second rings, with phosphate surface treatment on both rings and chrome on the oil ring rail for controlled wear characteristics. If you are sourcing piston rings for a Buick Century, Chevrolet Camaro, or Jeep CJ7, part number 5570 is a fitment-specific option to verify against your engine build.

Installation Notes

Verify bore size, groove dimensions, and ring end gap before installation. Confirm the engine uses the listed deep oil groove configuration and standard bore specification. Match the ring set to the exact engine build and application details before assembly.

Quality Assurance

Part number 5570 cross-references Monroe Shocks & Struts (e.g., 457P, 465NP) for the same application. Review all fitment notes carefully, including the deep oil groove requirement and application-specific details, before installation.
