Fel-Pro HS26744PT is a PermaTorque cylinder head gasket set built for 5.3L GM truck and SUV head service where sealing surfaces may not be fresh from the machine shop. Proprietary coating, a stopper layer, and multi-layer stainless steel construction help the gasket maintain clamp load, seal combustion pressure, and manage the heat and surface finish challenges common in real-world repairs.

Fel-Pro HS26744PT Features:

• NextGen coating technology is designed to handle high engine temperatures and seal against surface finishes as rough as 80 Ra.
• LaserWeld stopper layer technology reinforces the combustion seal and helps reduce the risk of gasket blowout under cylinder pressure.
• Multi-layer stainless steel construction helps maintain sealing stress while allowing for cylinder head lift during engine operation.
• Embossed sealing beads are placed at critical fluid and combustion areas to help close potential leak paths.
• 100.2 mm cylinder bore diameter supports proper fit on the specified 5.3L V8 applications.

Use during cylinder head removal, head gasket replacement, or top-end service on the supported GM 5.3L truck and SUV platforms. Follow the factory service procedure and replace any required torque-to-yield fasteners or related sealing components not supplied with the set.

Fits select 5.3L V8 applications on 2014-2019 Chevy Silverado 1500 and GMC Sierra 1500, 2019 Chevy Silverado 1500 LD and GMC Sierra 1500 Limited, plus 2015-2020 Chevy Tahoe, Suburban, GMC Yukon, and Yukon XL. Confirm engine, year, and vehicle configuration before installation.
