Customer Questions & Answers

  • Question: What are the specifications of the 551696 Exhaust Manifold Bolts?

    Answer: The 551696 Exhaust Manifold Bolts are designed specifically for GM LS series engines, including LS1, LS2, LS3, LSX, and LT models. Made from durable materials, these bolts ensure a secure and long-lasting fit for exhaust manifold installations. Their precise dimensions and thread design match factory specifications, facilitating optimal sealing and performance. By using these bolts in your engine setup, you can achieve reliable performance and avoid exhaust leaks, which is critical for both daily drivers and high-performance builds.
  • Question: Can I use these bolts with aftermarket exhaust manifolds?

    Answer: Yes, the 551696 Exhaust Manifold Bolts can typically be safely used with aftermarket exhaust manifolds designed for GM LS engines. They are engineered to work with common flange designs found in aftermarket products, providing a strong and reliable connection. However, it's always advised to check the specifications of the aftermarket manifold to ensure compatibility. This approach helps maintain exhaust integrity and prevents performance issues, especially in modified setups often seen in tuners and racers.
  • Question: How many bolts come in a set of the 551696 Exhaust Manifold Bolts?

    Answer: The 551696 set includes 12 pieces of exhaust manifold bolts, which is usually enough for a complete installation on a GM LS engine. This quantity is designed to accommodate dual exhaust manifold setups commonly found in V8 applications. Ensuring you have the right number of bolts is essential to properly secure your exhaust manifolds, which prevents loosening due to engine vibrations and thermal expansion, thereby maintaining engine performance over time.
  • Question: What is the material used for these exhaust manifold bolts?

    Answer: The 551696 Exhaust Manifold Bolts are typically made from high-strength carbon steel, which provides excellent durability and resistance to corrosion. This material choice is important due to the harsh conditions that exhaust components endure, including high temperatures and exposure to exhaust gases. The robust construction helps to ensure the bolts won't stretch or break under pressure, making them an ideal choice for both stock and performance applications.
  • Question: Are these bolts compatible with all LS engine models?

    Answer: While the 551696 Exhaust Manifold Bolts are compatible with most GM LS engine models including LS1, LS2, LS3, LSX, and LT series, it is essential to verify the specific requirements of your engine model. Some engine configurations may have unique bolt lengths or patterns, so checking compatibility with your specific engine variant can prevent installation issues. This due diligence helps maintain engine reliability and function, making it crucial for your vehicle's performance.
  • Question: Do I need any special tools to install these manifold bolts?

    Answer: Installing the 551696 Exhaust Manifold Bolts generally requires standard hand tools, along with a torque wrench to ensure proper tightening. Using a torque wrench is important to avoid overtightening, which can damage components or cause leaks. If you're performing the installation yourself, also having a socket set and possibly extensions can help access bolts in tight spaces. This practice is crucial in maintaining engine integrity and avoiding future repair issues.
  • Question: Can these bolts prevent exhaust leaks effectively?

    Answer: Yes, the 551696 Exhaust Manifold Bolts are designed to secure the exhaust manifold tightly, thus minimizing the chances of exhaust leaks. Proper installation of these bolts creates a tight seal with the exhaust manifold and gasket, essential for optimal engine performance. This is particularly critical in high-performance applications where exhaust flow management directly affects horsepower and engine efficiency. Maintaining this seal is paramount for any engine setup.
  • Question: What is the torque specification for installing these bolts?

    Answer: The torque specification for the 551696 Exhaust Manifold Bolts typically aligns with manufacturer recommendations, usually around 18-25 lb-ft, although this may vary based on the specific engine setup. It's vital to follow a proper torque sequence to ensure even clamping pressure throughout the manifold. This practice helps prevent warping of the manifold and ensures proper exhaust flow, reducing the risk of performance issues. Always double-check torque specs based on your application before proceeding.
  • Question: Where can I buy the 551696 Exhaust Manifold Bolts?

    Answer: You can buy the 551696 Exhaust Manifold Bolts from Ubuy in Isle of Man. Ubuy specializes in a wide range of automotive parts and accessories, ensuring quality products are available for your needs. Their user-friendly platform allows for easy searching and comparison, making it convenient to find the right parts for your automotive projects. Whether you're a DIY enthusiast or a professional mechanic, Ubuy can deliver the parts you require for optimal engine performance.
  • Question: What gaskets are compatible with the 551696 Exhaust Manifold Bolts?

    Answer: The 551696 Exhaust Manifold Bolts are designed to work seamlessly with GM 12617944 Exhaust Manifold Gaskets, which are specifically engineered for LS series engines. Using the correct gaskets in conjunction with these bolts is crucial to achieving a proper seal and preventing exhaust leaks. This compatibility ensures a solid connection between the exhaust manifold and engine block, ultimately enhancing performance and longevity of the exhaust system, especially in performance-oriented applications.
