    Product Description

    Michigan Motorsports L83 / L84 5.3L Gen V Head Gasket & Bolt Set

    Fits 2014-Later Gen V 5.3L Engines | L83 • L84 • L82 • L8B

    The Michigan Motorsports L83/L84 5.3L Head Gasket and Bolt Set is a complete, OEM-equivalent solution for Gen V LS engine rebuilds and repairs. This kit includes high-quality multi-layer steel (MLS) head gaskets manufactured by the same source as the OEM GM units, along with stock-replacement head bolts designed to meet factory torque specifications. Ideal for maintaining proper sealing, durability, and long-term reliability, this set is perfect for stock rebuilds, top-end refreshes, or head gasket replacement on 2014-newer 5.3L Gen V engines.

    Key Features & Benefits

    • OEM-Equivalent MLS Head Gaskets: Manufactured by the same supplier as GM OEM gaskets, delivering factory-level fit, sealing performance, and reliability.
    • 5-Layer Multi-Layer Steel Construction: Provides superior strength, durability, and resistance to heat and cylinder pressure compared to composite gaskets.
    • Complete Head Bolt Set Included: Stock-replacement Michigan Motorsports head bolts designed to be torqued to OEM specifications for proper clamping force.
    • Correct Hardware Configuration: Includes 19 standard bolts and 1 Allen-head bolt required for the driver-side front cylinder head location.
    • Ideal for Stock Rebuilds: Perfect for factory-style repairs, engine refreshes, or head gasket replacement on Gen V 5.3L engines.

    Head Gasket Specifications

    • Bore Diameter: 3.840"
    • Compressed Thickness: .054"
    • Construction: 5-Layer MLS (Multi-Layer Steel)

    Kit Includes

    • 2 Head Gaskets: MLS gaskets for both cylinder heads.
    • Head Bolt Set: 19 standard bolts and 1 Allen-head bolt for correct installation.

    Key Fitments (5.3L Models Only)

    • Chevrolet Silverado 1500: 2014–2024
    • Chevrolet Suburban: 2015–2024
    • Chevrolet Tahoe: 2015–2024
    • GMC Sierra 1500: 2014–2024
    • GMC Yukon: 2015–2024
    • GMC Yukon XL: 2015–2024

    NOTE: On these engines it is highly recommended to clean out the head bolt threads in the block with a chaser such as ARP 912-0016 (click here) due to the thread compound that was used on the factory bolts. Failure to do so can result in new fasteners stretching or breaking before reaching final torque.
