Description

You can try to install your headers with ordinary hardware, but it's not advisable. If it isn't impossible, it will be very difficult. However, Trans-Dapt Performance header bolts neatly solve the problem. They're specifically designed for the task. They're made from strong Grade 5 steel and have smaller-than-standard hex heads to make tightening in those difficult spots a whole lot easier.
