Restore Engine Compression: Ultimate Top-End Head Gasket & Bolt Overhaul Kit for GM 3.6L LLT / LFX V6

Are you dealing with a blown head gasket, loss of engine compression, or coolant leaks in your GM vehicle? These are classic symptoms of top-end degradation common in high-mileage 3.6L LLT and LFX DOHC V6 engines. Left unaddressed, a leaking head gasket can cause severe engine overheating and catastrophic internal valvetrain damage. Restore your engine's factory compression, structural reliability, and leak-free operation with this Ultimate Top-End Overhaul Kit. Engineered strictly for the highly popular 2009-2016 GM 3.6L V6 platforms, this comprehensive package provides every premium component needed for a permanent, professional top-end rebuild.

Sourcing high-quality gaskets and critical cylinder head bolts separately can be incredibly expensive and carries the risk of mismatched parts. This premium master overhaul package maximizes the value of your teardown by conveniently matching high-performance Multi-Layer Steel (MLS) head gaskets with a complete set of brand-new bolts. Meticulously flat-packed to protect the integrity of the rigid MLS layers during transit, this kit ensures a perfect, heavy-duty seal built to withstand extreme combustion pressures.

Key Features & Included Components:

Premium MLS Head Gaskets: Includes left and right Multi-Layer Steel (MLS) cylinder head gaskets engineered to withstand extreme heat and high combustion pressures.

Complete TTY Head Bolt Set: Comes with a full set of brand-new Torque-to-Yield (TTY) long and short cylinder head bolts built to strict ES72274 specifications for permanent clamping force.

Full Intake & Exhaust Gaskets: Features a complete upper intake manifold (plenum) gasket set, a lower intake manifold gasket set, and heavy-duty MLS exhaust manifold gaskets to fully seal the breathing paths.

Complete Valvetrain Sealing: Includes 2x valve cover gaskets with integrated spark plug tube seals, a front camshaft seal, and a complete assortment of necessary O-rings and valve stem seals.

(⚠️ CRITICAL FITMENT NOTE: This top-end overhaul kit is engineered STRICTLY for 2009-2016 GM 3.6L V6 DOHC platforms equipped with the LLT or LFX engine codes. It flawlessly fits specified years of the Chevrolet Traverse, GMC Acadia, Buick Enclave, and Saturn Outlook. Please carefully verify your vehicle's exact year, displacement, and engine code before purchasing to ensure proper fitment.)
