Product Description
Michigan Motorsports LS Valve Stem Seal Kit - 16 Seals for Stock-Diameter Powdered-Metal and Bronze Valve Guides
For Gen III/IV 4.8L 5.3L 5.7L 6.0L 6.2L LS and Vortec V8 Engines with Common Dual Valve Spring Setups
Complete the valvetrain in your Gen III or Gen IV LS engine with this 16-piece valve stem seal kit from Michigan Motorsports. Designed for cylinder heads using stock-diameter powdered-metal or bronze valve guides, these seals help control unwanted oil around the valve stems and keep it from entering the combustion chambers. Their application makes them a common choice for compatible LS and Vortec cylinder-head builds using dual valve springs and separate spring locators.
Key Features & Benefits
- Complete 16-Seal LS Engine Kit: Includes 16 valve stem seals to service the intake and exhaust valves in one compatible LS or Vortec V8 engine. The complete set keeps all required seals together for a cylinder-head rebuild, valvetrain upgrade or dual valve spring installation.
- Stock-Diameter Valve Guide Compatibility: Designed for compatible cylinder heads equipped with stock-diameter valve guides. These LS valve seals can be used with the powdered-metal guides found in many factory-style applications or with compatible bronze replacement guides.
- Commonly Used with Dual Valve Springs: A practical valve seal option for many performance LS cylinder-head combinations using dual valve springs. Their guide-specific application allows the seals to be paired with the separate spring locators required by the valvetrain setup.
- Controls Oil Around the Valve Stems: Valve stem seals regulate oil at the valve-guide interface and help prevent unwanted engine oil from traveling into the combustion chamber. Replacing worn or missing seals restores this essential oil-control component during cylinder-head service.
- Broad Gen III and Gen IV LS Coverage: Intended for compatible 4.8L, 5.3L, 5.7L, 6.0L and 6.2L LS-based V8 engines. Supplied engine-family coverage includes popular LS1, LS2, LS3, LS6, LS7, LSA and Vortec truck-engine applications.
Notes
- A separate valve spring locator is required when these seals are used with dual valve springs.
- Spring locators are not included with the 16-piece valve seal kit.
