The Head Bolt Set 04-16 Chevy LS is a critical engine fastening solution engineered for builders, mechanics, and enthusiasts working on LS-platform powerplants. Whether you're performing routine maintenance, rebuilding after a high-mileage teardown, or assembling a modified long-block, this OEM-equivalent fastener set ensures proper clamping force and cylinder head sealing. The 04–16 model years span multiple LS variants—including LS2, LS3, and LS7 generations—making this set a versatile choice for Gen III and Gen IV engine work.
Manufactured by MAHLE ORIGINAL/CLEVITE under MPN GS33449, these head bolts deliver the precise specifications required for correct head gasket preload and combustion chamber sealing. LS-platform engines depend on consistent torque-to-yield fastening, and these bolts are engineered to OEM tolerances to maintain structural integrity under sustained boost, nitrous, or naturally aspirated power. The set weighs 2.165 lbs and ships in compact 6.45 × 2.35 × 6.8-inch packaging, making storage and transport convenient for shop environments.
Technicians restoring stock engines, tuners upgrading to forged pistons or higher compression ratios, and engine builders preparing fresh blocks all benefit from OEM-quality fasteners that won't compromise gasket sealing or cylinder head clamping. Installation requires proper torque sequence and angle-of-turn methodology—consult your engine's service manual or build guide for exact specifications. For LS swaps, LS1 restorations, or performance builds, using factory-equivalent head bolts eliminates guesswork and ensures your investment in gaskets, machine work, and components performs reliably for years of driving.
