    Product Description

    Michigan Motorsports 4.8L / 5.3L LS Performance Piston Ring Set – Standard Bore

    Fits 1999–2013 LS-Based 4.8L & 5.3L Engines | Stock Bore & OEM Pistons

    The Michigan Motorsports LS Performance Ring Set is engineered for builders who want maximum durability and oil control from a stock-bore short block. Designed specifically for OEM GM 4.8L and 5.3L LS pistons, this file-fit performance ring package is ideal for turbocharged, supercharged, nitrous-assisted, or high-output naturally aspirated applications. Featuring a gas-nitrided steel top ring, Napier-style second ring, and nitrided standard-tension oil rings, this set delivers superior sealing, reduced blow-by, and long-term reliability under extreme cylinder pressures.

    Key Features & Benefits

    • Gas-Nitrided Steel Top Ring: Provides exceptional heat resistance and strength compared to traditional moly-faced iron rings, making it ideal for boosted and high-cylinder-pressure applications.
    • Napier-Style Second Ring: Phosphate-coated iron Napier design delivers superior oil scraping and control, reducing oil consumption and improving ring seal.
    • Standard-Tension Oil Ring Package: Nitrided steel oil rails with standard-tension expander provide excellent oil control while minimizing friction and bore wear.
    • Power Adder Ready: Designed for turbo, supercharger, and nitrous applications with included guidance for proper ring end-gap setup under boosted conditions.
    • Stock Bore OEM Compatibility: Engineered to fit factory GM pistons in standard 4.8L and 5.3L LS engines; may also fit select aftermarket pistons with verification.
