<p><strong>GM LS Cast Aluminum Valve Covers with Coil Mounts for Sealing, Clearance, and Engine Bay Detail</strong></p><p>These GM LS valve covers are built around the details buyers search for most: fitment, valve cover height, material, finish, ventilation, and sealing. The 3 in. profile, center bolt mounting style, and application-specific top style help match the cover to the correct engine build and clearance requirements.</p><p>These cast aluminum valve covers are available in polished, satin, or black finishes to enhance both durability and engine bay appearance. Built-in coil mounting provisions and internal baffling provide ignition system compatibility and effective oil control. Be sure to verify gasket and hardware requirements for your specific engine combination before installation.</p><p>The integrated coil mounting studs allow Delco D510C (GM Gen V LS) ignition coils to bolt directly to the valve covers using the factory 72mm mounting pattern—no separate coil relocation or mounting brackets required. TSP 81015-8 ignition coils are a direct-fit option for these valve covers.</p><p>Use these valve covers for street performance builds, restorations, swaps, and engine dress-up upgrades where appearance, oil control, and valvetrain clearance matter. Verify gasket style, breather/PCV layout, rocker clearance, and hood clearance before installation.</p><p><strong>COMPATIBLE WITH</strong><br>GM LS SERIES V8 ENGINES<br>• 4.8L / 293 in³ (LR4, LY2)<br>• 5.3L / 325 in³ (LM7, L59, L33, LC9, LH6, LY5, LMG)<br>• 5.7L / 346 in³ (LS1, LS6)<br>• 6.0L / 364 in³ (LQ4, LQ9, LY6, L76, L96)<br>• 6.2L / 376 in³ (LS3, L92, L99)<br>• 7.0L / 427 in³ (LS7)</p><p><strong>NOTES</strong><br>Verify valve cover height, coil mount configuration, breather/PCV routing, and rocker arm clearance before installation.</p><p><strong>COMMON VEHICLE APPLICATIONS</strong><br>Chevrolet Silverado / GMC Sierra (LS equipped)<br>Chevrolet Camaro / Corvette (LS equipped, including LS7 Z06)<br>Chevrolet Tahoe / Suburban / Yukon (LS equipped)<br>Pontiac GTO / G8 (LS equipped)</p><p><strong>SPECIFICATIONS</strong><br>Mounting Style: Center Bolt<br>Finish: Black<br>Internal Height: 1.6 In.<br>Overall Height: 3 In.<br>Baffled: Yes<br>Cover Material: Cast Aluminum<br>Gasket Style: Included One-Piece O-Ring<br>Valve Cover Hardware: Included<br>Quantity: 2<br>Valve Cover Bolts: Included<br>Matching Oil Fill Cap: Included<br>Valve Cover Gaskets: Included<br>Coil Mount Type: Integrated 72mm Coil Mounts<br>Compatible Coil Style: Delco D510C / TSP 81015<br>Coil Brackets Required: No</p>
