ARP Timing Cover Bolt Kit Small Block Chevy 3/8″ Hex Bolt Set

Description

Product Overview

The ARP Timing Cover Bolt Kit is a purpose‑built solution for Small Block Chevrolet engines, delivering a precise 3/8‑inch hex bolt that meets the demanding standards of performance and durability. Each bolt is manufactured from Grade 8 alloy steel, offering exceptional tensile strength that resists stretching and deformation under high‑load conditions. The bolts feature a painted finish that not only enhances corrosion resistance but also provides a sleek, professional appearance that matches the engine bay aesthetics. Designed with a hex head for easy torque application, the kit includes all necessary components to replace worn or damaged bolts, ensuring a secure seal on the valve cover and preventing oil leaks.

Beyond the core specifications, the kit reflects ARP’s commitment to engineering excellence. The bolts are produced in a controlled environment, where each piece undergoes rigorous testing for hardness, dimensional accuracy, and thread integrity. This meticulous process guarantees that every bolt conforms to the 1A thread class and right‑hand thread style, delivering consistent performance across a range of operating temperatures. The kit’s lightweight design, weighing just 2.82 ounces per bolt, simplifies handling during installation while maintaining the robustness required for high‑performance applications.

Installation is straightforward thanks to the hex head design, which works seamlessly with standard torque wrenches and socket sets. The kit includes a comprehensive set of instructions that guide users through the removal of old bolts, cleaning of the mating surfaces, and proper torque sequencing. By following the recommended torque values, mechanics can achieve an optimal seal that minimizes the risk of valve cover distortion and ensures long‑term reliability. The kit’s compatibility with OEM part numbers (400‑1502, 4001502) makes it an ideal replacement for original equipment, offering a direct upgrade path without the need for additional modifications.

In addition to its functional attributes, the ARP Timing Cover Bolt Kit provides value through its cost‑effective pricing and the reputation of the ARP brand. Priced at $25.24, it offers a premium solution that rivals higher‑priced alternatives, delivering the same level of quality and performance expected from top‑tier automotive fasteners. Whether you are restoring a classic Chevrolet engine or upgrading a modern performance build, this kit delivers the confidence of a secure, leak‑free valve cover every time.

Usage

This bolt kit is ideal for both professional automotive technicians and dedicated hobbyists who work on Small Block Chevrolet engines. It excels in applications ranging from routine maintenance, such as valve cover replacement during a standard service interval, to high‑performance builds where engine reliability is paramount. The Grade 8 bolts are particularly suited for engines that experience elevated combustion pressures, such as those equipped with performance camshafts, upgraded intake manifolds, or forced induction systems.

When installing the kit, it is recommended to clean all mating surfaces thoroughly to remove any residual oil, carbon deposits, or old gasket material. Applying a thin layer of high‑temperature RTV silicone sealant to the bolt threads can further enhance sealing performance, especially in environments where thermal expansion is significant. The hex head design allows for precise torque application, ensuring that each bolt is tightened to the manufacturer‑specified value, typically around 18‑22 ft‑lb for Small Block Chevy valve covers.

Beyond the engine bay, the kit’s robust construction makes it suitable for use in off‑road and racing scenarios where vibration and shock loads are more intense. The painted finish resists rust and corrosion even when exposed to moisture, road salt, or high‑humidity conditions, extending the service life of the fasteners. Whether you are assembling a street‑legal vehicle, a track‑day racer, or a restoration project, the ARP Timing Cover Bolt Kit provides the reliability and peace of mind needed for demanding automotive environments.
