AUTOBABA 5.3L Full Cylinder Head Gasket Kit with 30 ES72220 Bolts — MLS Gaskets & Valve Stem Seals for GM 2005–2014

AUTOBABA's 5.3 full cylinder head gasket kit is a complete replacement set that includes multi-layer steel head gaskets, 30 ES72220 head bolts, and all related seals and gaskets needed to rebuild GM 5.3L V8 cylinder heads for model years listed.

If you're servicing a 5.3L V8 from Buick, Chevrolet, GMC or compatible platforms, this kit delivers the components required to reseal the heads and valley while replacing wear-prone parts. The package groups MLS head gaskets, head bolts, valve stem seals, intake and exhaust gaskets, oil pan and valley cover gaskets plus assorted O-rings and seals so you can complete a head or top-end job without sourcing many separate parts.

Which vehicles and engines does this kit fit?

This AUTOBABA kit is engineered for GM 5.3L engines across multiple model years and makes. It matches the common 5.3L head and valley sealing patterns used by Buick, Chevrolet and GMC, plus some rebadged models.

• Chevrolet: Avalanche 2007–2013; Silverado 1500/Classic 2005–2013; Suburban and Tahoe 2007–2014; Trailblazer Ext 2005–2006, Trailblazer 2006–2008
• Buick/GMC/Other: Buick Rainier 2005–2007; GMC Envoy/Envoy XL/XUV 2005–2009; Sierra/Yukon 2005–2014; Isuzu Ascender 2005–2006; Saab 9-7x 2005–2009
• Intended for standard GM LH/LM series 5.3L V8 heads—compare part shapes and bolt patterns before purchase

What parts are included and why are they useful?

The kit bundles the core gaskets and hardware needed for a reliable head service, reducing returns to the parts counter and ensuring matched sealing materials throughout the assembly.

• Multi-layer steel (MLS) head gaskets sized for GM 5.3L combustion chambers
• 30 ES72220 torque-to-yield style cylinder head bolts for correct clamp force
• Valley cover and engine oil pan gaskets to reseal the lower deck
• Intake and exhaust manifold gaskets, valve stem seals, crankshaft rear seal, damping plug heads, fiber base plates and assorted O-rings

How does this kit help prevent common engine leaks?

Quality materials and OEM-style components restore compression and fluid sealing where gaskets and seals have aged or been damaged. Properly replacing both gaskets and bolts reduces the chance of future leaks caused by reused or stretched fasteners.

• MLS gaskets resist high combustion pressures and temperature cycling
• New head bolts ensure consistent clamping torque across the head
• Complete valve stem and manifold gaskets eliminate multiple leak sources at once
• Includes crankshaft rear seal and oil pan gasket for a full top-to-bottom reseal

What should I check before ordering and installing this kit?

Confirm compatibility by matching your engine code, head bolt count and gasket shape to the kit contents. Inspect the head and block for warpage or cracks—gaskets cannot correct a damaged sealing surface.

• Verify year, make and model fitment against your VIN and engine stamping
• Measure deck flatness and check for cracks in heads and block
• Use the included ES72220 bolts as single-use items where required by OEM torque-to-yield specs
• Follow a correct torque sequence and tightening procedure during assembly

Who is this for: Technically minded DIY mechanics, professional technicians and restoration shops working on GM 5.3L V8 engines who want a single, comprehensive gasket and bolt set to complete a cylinder head service. Choose this kit when you want matched gaskets and hardware to reduce parts sourcing time and help achieve a consistent reseal across the top end.
