E-Series Head Bolt Kit Jeep 4.0L I6

The E-Series Head Bolt Kit Jeep 4.0L I6 from Edelbrock is specifically designed for builders and enthusiasts who require reliable clamping force and fastener integrity in their Jeep inline-six engine builds. This kit is essential for those refreshing a stock AMC 4.0L engine or working on a modified powerplant, ensuring proper head bolt specification for optimal cylinder head sealing and long-term reliability.

Engineered to meet the specific torque and stretch characteristics of the Jeep 4.0L I6 architecture, this kit ensures consistent gasket compression and prevents head lift under high-rpm conditions. The fasteners are made from premium alloy steel, designed to meet or exceed OEM specifications, providing superior preload retention across thermal cycles. This is crucial for maintaining clamping load as aluminum heads expand and contract during engine operation.

Ideal for those restoring or upgrading Jeep TJ, XJ, ZJ, or WJ models equipped with the iconic 4.0L I6 engine, this kit is a must-have for any head removal work or inspections. Its straightforward design allows for precise torque-to-yield installation using standard hand tools, ensuring repeatable results for stock engine configurations.
