Key Features & Benefits
- MLS Exhaust Gasket Construction: Multi-layer steel construction helps provide a dependable seal between the cylinder head and exhaust manifold or compatible header flange. The MLS design is well-suited for LS engines exposed to heat, vibration, and repeated exhaust system service.
- Fits Gen 3 & Gen 4 LS Engines: Designed for broad LS compatibility, including popular 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L Gen 3 and Gen 4 LS-based V8 applications. This makes them a practical gasket set for repairs, swaps, rebuilds, and exhaust service.
- Like GM #12617944: Precision-engineered as an OEM-style replacement gasket option matching GM-style fitment like 12617944. This supports straightforward installation when replacing factory exhaust manifold gaskets on compatible LS engines.
- Pair Included for Both Cylinder Heads: Includes two MLS exhaust manifold/header gaskets, giving you the correct quantity for both sides of one LS V8 engine. This helps keep the repair organized and avoids needing to purchase separate left and right side gaskets.
- Great for Stock Repairs & LS Swaps: Ideal for exhaust manifold replacement, header installation, engine rebuilds, cylinder head service, LS swaps, and general exhaust gasket replacement on compatible Gen 3 and Gen 4 LS platforms.
