Head Studs Bolts Kit For 2004-2020 Chevy GM 4.8L 5.3L 5.7L 6.0L 6.2L 7.0L 🔧 Cylinder Head Screw Set – For Chevy LS Engines (2004–2018) | LS1/LS6/4.8L/5.3L/5.7L/6.0L 🔧 【200,000 PSI Strength | 12-Point Head | Includes Washers & Nuts】Prevents Gasket Failure & Ensures Uniform Load Distribution 1. Core Features 🔹 Wide Compatibility – 2004–2018 Chevy LS-Series Engines Engineered as a direct replacement for cylinder head fasteners in Chevy’s iconic LS V8 engines, covering passenger cars, trucks, and performance builds. Ideal for engine rebuilds, head gasket replacements, or performance upgrades, with key compatible engines: Engine Family Engine Displacement Compatible Years Typical Vehicle Applications LS1/LS6 5.7L V8 2004–2018 Camaro, Corvette, GTO LS-Series 4.8L V8 2004–2018 Silverado 1500, Sierra 1500, Tahoe 5.3L V8 2004–2018 Silverado 1500, Suburban, Yukon, Avalanche 6.0L V8 2004–2018 Silverado 2500 HD, Sierra 2500 HD, Escalade Critical Compatibility Note : Designed for 2004 and newer LS engines – confirm your engine’s production year and displacement (e.g., 5.3L vs. 6.2L) before purchasing (6.2L LS engines require a different fastener set). 🔹 200,000 PSI Strength – Industrial-Grade Durability Built to withstand the extreme pressure and heat of LS engine combustion chambers, far exceeding OEM fastener standards: Cold Forging Process : Creates a dense molecular structure in the bolts (eliminates weak points) – ensures they don’t stretch or snap under high cylinder pressure. Heat Treatment : Bolts are heat-treated before thread rolling and machining – achieves a nominal tensile strength of 200,000 PSI (stronger than OEM’s ~170,000 PSI fasteners). Black Oxide Finish : Provides corrosion resistance (prevents rust from engine oil, coolant, and moisture) – maintains performance even in harsh underhood conditions. 🔹 12-Point Head & Hardened Washers – Optimized for Performance Features design upgrades that simplify installation and improve reliability vs. stock bolts: 12-Point Head : Eliminates the need to disassemble valve train components (e.g., rocker arms) to access cylinder head bolts – saves hours of labor during engine rebuilds. Large-Area Flange : Distributes clamping force evenly across the cylinder head – avoids warping or uneven pressure (a common cause of head gasket failure). Hardened Parallel Ground Washers : Included with every bolt to ensure precise torque readings (no “give” from soft washers) and uniform load distribution – prevents gasket leaks by keeping pressure consistent. 🔹 Prevents Head Gasket Failure – Extra “Stretch” for Sealing LS engines (especially high-mileage or performance-built units) often suffer from head gasket leaks due to insufficient bolt stretch. This set solves the issue by: Providing controlled “stretch” (within safe limits) to maintain consistent clamping force on the head gasket – compensates for gasket compression over time. Supporting larger-diameter valve springs (common in performance builds) – the robust fasteners handle the extra pressure from upgraded valvetrains without compromising head gasket seal. 2.

Package Included 20 × Long Cylinder Head Studs 10 × Short Cylinder Head Studs 30 × Hardened Parallel Ground Washers 30 × Matching Nuts 4. Important Installation & Usage Tips Installation Guidelines Professional Installation MANDATORY : Cylinder head bolts require precise torqueing (follow GM’s factory specs: typically 22 ft-lbs initial, then 90°–120° additional turn) and a crisscross pattern. Improper torque causes head gasket leaks, cylinder head warping, or bolt failure. Key Prep Steps : Clean bolt holes in the engine block thoroughly (remove old oil, debris, or thread sealant) – ensures accurate torque readings. Apply a small amount of thread locker (e.g., Loctite 243) to bolt threads (avoid getting locker on the washer or gasket surface) – prevents bolts from loosening due to engine vibration. Use a torque wrench with a 12-point socket – ensures proper engagement with the bolt head (avoids stripping). Post-Installation Check After installation, allow the engine to idle for 30 minutes (to bring it to operating temperature) – then recheck torque on all bolts (thermal expansion can slightly reduce torque). For performance builds, retorque bolts after the first 500 miles of use – ensures clamping force remains consistent after initial break-in. 5. After-Sales Support Fitment Questions : If you’re unsure if the set fits your LS engine (e.g., 2003 vs. 2004 model year), contact the seller with your engine code (found on the block) – they’ll confirm compatibility ASAP. Defects/Issues : If bolts arrive damaged, stripped, or missing, reach out to the seller for a replacement set – no hassle refunds or exchanges for defective parts. The ultimate cylinder head fastener set for LS engine rebuilds! This high-strength kit ensures reliable head gasket sealing, supports performance upgrades, and saves labor with its 12-point design – a must-have for DIY rebuilders and professional mechanics. 🚗⚙️
