BBTV 592 Engine Piston Ring

Engine Piston Ring for V8 Applications

This engine piston ring set is built around standard bore dimensions and OE-style ring materials for a wide range of classic and light-duty truck applications. Part number 592 is specified for 4.000-inch bore engines and uses phosphate and chrome surface treatments to support ring seating and wear control.

• Standard oversize specification for 4.000-inch engine bores
• Top ring and second ring made from grey iron for consistent sealing performance
• Chrome-treated first oil ring rail with stainless expander for oil control
• Phosphate-treated top and second rings for improved break-in characteristics
• Configured for six-cylinder engine applications listed in the fitment data

Detailed Fitment and Design

Part number 592 is an engine piston ring set with a 5/64 top groove, 5/64 second groove, and 3/16 first oil groove. The ring package combines grey iron top and second rings with phosphate surface treatment, plus a chrome-treated oil ring rail and stainless expander for durability and stable cylinder sealing. This part number 592 application coverage includes Chevrolet Astro, GMC Safari, Ford F-150, and Chevrolet S10 among many others, making it a broad fitment option for older domestic engines with a 4.000-inch bore.

This part cross-references Sealed Power (e.g., 272AP, H519P) for the same application.

What It Is Used For

• Restoring compression loss caused by worn piston rings
• Reducing oil consumption from ring wear or poor oil control
• Improving cylinder sealing after engine rebuild work
• Addressing blow-by related to worn ring lands or ring faces
• Supporting proper break-in on standard bore engine rebuilds

Installation Notes and Tips

Verify bore size, groove dimensions, and ring end gap before assembly. Clean the piston ring grooves thoroughly and confirm the cylinder finish matches the ring material and surface treatment. Because fitment spans many Chevrolet, GMC, and Ford applications, confirm the engine code and bore specification against the vehicle build data before installation.

Quality Assurance

Part number 592 is specified with OE-style materials and surface treatments commonly used in engine rebuild service. The listed fitment data and dimensional attributes should be matched to the engine during teardown and measurement to confirm correct application.
