GM LS1 Piston Ring Set 5.7L 97-04

The GM LS1 Piston Ring Set 5.7L 97-04 by Sealed Power is a complete ring kit engineered for General Motors LS1 V8 engines across the 1997–2004 production years. This is a drop-in replacement piston ring set designed to restore compression, reduce blow-by, and improve ring seal integrity in high-mileage or rebuilt LS1 engines. Sealed Power's moly-coated steel construction delivers reliable performance across street, mild performance, and restoration applications.

The kit features a 3.907-inch bore specification with precision ring thicknesses of 1.5 x 1.5 x 3.0 mm, maintaining standard tension for consistent ring-to-bore contact and minimal oil consumption. Moly plating on the ring face reduces initial wear during engine startup and break-in, protecting against scuff and improving longevity. This eight-cylinder ring set is manufactured to OEM tolerances, making it suitable for engine rebuilds, overhauls, and high-mileage replacement applications where factory-spec fitment and performance are required.

This product is intended for LS1-powered vehicles, including Chevrolet Corvette (C5), Camaro (fourth generation), Pontiac GTO, and other 5.7L LS1 applications from 1997 through 2004. Buyers rebuilding or restoring LS1 engines benefit from Sealed Power's OEM-equivalent quality control and compatibility assurance. The drop-in design minimizes fitment complexity, though proper piston ring installation procedure and correct end-gap filing (if required by local specifications) are essential for optimal sealing and engine longevity.
