Edelbrock Jeep 4.0L I-6 E-Series Head Bolt Kit

Edelbrock is a well-known name in performance engine parts, and their E-Series head bolt kit is built to match that reputation. This kit, part number 85332, is specifically made for Jeep 4.0L inline six engines that use 1/2-inch head bolts. It's a great choice if you're pairing it with Edelbrock's own cylinder heads, like their #50159 or #50169, but it will also work with the 4.2L inline six if you're using their heads on that engine.

What makes these bolts stand out is their strength. They have a yield tensile strength of 190,000 PSI, which means they can handle the loading reliably. Edelbrock achieves this by rolling the threads after heat-treating, giving them a superior form and added strength. You'll also notice the small hex head, which is a practical touch that gives you more room to work with your socket in tight engine bays. Plus, they come with a durable black oxide finish that includes a sealer, and each bolt head is stamped with the distinctive Edelbrock E logo.
