LowPricedAutoParts Premium Silicone Umbrella Valve Stem Seal (3/8" Stem) - Fits Chrysler 318 360 440 Dodge Ram 20-Pack Intake/Exhaust

Keep your classic Chrysler, Dodge or Ram vehicle running clean and powerful with this premium silicone umbrella valve stem seal 20-pack from LowPricedAutoParts – the retailer of automotive parts and accessories that puts an emphasis on customer service. These seals (Stem Size 3/8", Seal OD .805", ID .750", Length .575") are precision-made for a wide range of vintage Chrysler applications, including 225 slant six, 273/318/340/360/383/400/440 LA big blocks and similar engines in cars, trucks and vans from the 1950s through 1990s. These iconic OHV engines delivered legendary torque and reliability in muscle cars, daily drivers and work trucks when properly maintained. Over decades, factory seals can harden, crack or wear from heat, oil and mileage – leading to high oil use, blue exhaust smoke, fouled plugs, valve guide damage or carbon buildup that reduces performance and shortens engine life in restored or still-running classics. This premium silicone replacement effectively corrects those problems, with umbrella-style design for reliable stem protection and silicone compound for excellent durability in high-heat, oil-exposed environments. The bulk 20-pack is perfect for full-head rebuilds, shop inventory or multiple projects. Installation during valve or head service: Clean valve stems and guides thoroughly, inspect for scoring (replace guides if worn), lightly lubricate, slide seals down stems without flipping the lip, confirm proper seating and no binding, reassemble rockers/arms to factory specs, and monitor oil consumption/smoke during break-in. Professional assistance is recommended for precise clearances and to handle any related valve/guide issues. At LowPricedAutoParts, customer service is our top priority. Send your VIN, exact year/model/engine/head details or any questions – our knowledgeable team responds quickly to confirm compatibility and provide guidance. Shop with confidence knowing these premium silicone umbrella valve stem seals are backed by our commitment to quality and support. We're here to help get your Chrysler 318, Dodge 360, Ram classic or similar vehicle sealed right and running strong – contact us today!
