A1 Technologies H11 Head Studs - Evo 8/9

Product Description

If you're looking to make big power (proven over 1000+whp) but don't like the idea of lifting your cylinder head and replacing head gaskets frequently these are exactly what you need! These studs are manufactured by A1 Technologies and utilize an H11 material that is much stronger than the typical 8740 chromoly and yields a tensile strength of 260,000 psi. They are also provisioned with a hex broach on the top of the stud enabling you to install them with the cylinder head on the car if necessary.

Part Number: 6-MITSU11MMHDSTD

Fits: Evo 8/9
