Customer Questions & Answers
-
Question:
What is included in the ARP Head Bolt Kit for GM LSA engines?
Answer: The ARP Head Bolt Kit for GM LSA engines typically includes high-quality head bolts, washers, and an installation lubricant. These head bolts are designed to provide superior clamping force and reliability compared to stock bolts. Using this kit ensures that your engine maintains peak performance, especially under high-stress conditions like racing or heavy towing. Users have found it essential for both performance upgrades and full engine rebuilds. -
Question:
How do I install the ARP Head Bolt Kit?
Answer: Installation of the ARP Head Bolt Kit involves removing the existing cylinder heads, cleaning the mating surfaces, and applying the provided lubricant to the bolts, followed by tightening them to the manufacturer's recommended torque specifications. Proper installation is crucial for engine integrity, ensuring that the heads are securely fastened. It's advisable to have some mechanical experience or consult a professional for installation, especially in a high-performance context. -
Question:
Why choose ARP for head bolts over OEM options?
Answer: ARP head bolts are engineered for superior quality and performance compared to OEM alternatives. They often feature higher tensile strength, improved material integrity, and better resistance to stretching, which results in a more secure clamping force. Many performance enthusiasts and professionals prefer ARP products to handle extreme conditions, such as high horsepower applications, ensuring that the engine remains reliable under stress. -
Question:
What advantages do 12pt head bolts have over 6pt ones?
Answer: 12-point head bolts provide increased engagement and tool access compared to traditional 6-point bolts. This means you are less likely to round off the bolt heads during installation or removal, which is especially useful in tight spaces. Additionally, the increased contact area distributes the load more evenly, enhancing overall torque accuracy and performance reliability in high-performance applications. -
Question:
Can I reuse my old head bolts with the ARP head bolt kit?
Answer: It is not recommended to reuse old head bolts with the ARP head bolt kit. Over time, head bolts can lose their structural integrity due to repeated stress and heat cycles, which could lead to failure. Using a fresh set of ARP bolts ensures optimal performance and safety, particularly in high-stakes engine builds where reliability is critical. -
Question:
Will the ARP Head Bolt Kit fit other GM engines?
Answer: The ARP Head Bolt Kit is specifically designed for GM LSA engines and may not fit other GM models without modifications. Each engine design has unique bolt specifications and dimensions, so using the right kit is essential for maintaining the engine's integrity. If you are considering using ARP bolts in a different engine, verify compatibility to avoid damage or performance issues. -
Question:
What is the torque specification for the ARP head bolts?
Answer: The torque specification for ARP head bolts can vary based on the specific engine design and application. Typically, ARP recommends referencing their installation instructions that come with the kit for precise torque values. It's crucial to follow the recommended torque sequence and specifications to achieve optimal clamping force and prevent head gasket failures, particularly in high-performance settings. -
Question:
Can I use the ARP Head Bolt Kit for racing applications?
Answer: Yes, the ARP Head Bolt Kit is designed to withstand the rigors of racing applications. Its high-quality materials and superior engineering make it ideal for extreme performance scenarios where standard bolts might fail. Many racers have successfully used ARP products to enhance engine reliability under high compression, ensuring that the engine operates at its best during competitive events. -
Question:
What materials are used in the ARP head bolts?
Answer: ARP head bolts are typically made from premium-grade steel alloys, often featuring a higher tensile strength than conventional bolts. This advanced material selection helps to resist stretch and fatigue, making them suitable for high-performance and high-stress applications. The precision machining also leads to a better fit and finish, contributing to enhanced overall engine durability. -
Question:
Where can I buy ARP Head Bolt Kit - 12pt GM LSA?
Answer: You can purchase the ARP Head Bolt Kit - 12pt GM LSA from Ubuy, which offers a wide selection of automotive performance parts. Ubuy ensures a reliable shopping experience, making it easy to find your required products with excellent customer service and support.
