_______

A serious clamping-force upgrade for the 1.5T platform, aimed at higher-mileage engines, tuned cars, or anyone refreshing the head gasket. Inline Pro's high-grade super alloy is heat treated and tested to a minimum 230 KSI tensile strength, giving boosted L15 builds the strength they need without the hydrogen embrittlement risk that comes with L19/H11 material.

The true-beam design runs the full length of the stud rather than necking down or undercutting, which means more consistent clamping force and reliable torque values — with 1.50 inches of thread engagement into the block for a properly secured cylinder head.

Kit Includes

• Head studs, nuts, washers
• Assembly lube
• Installation instructions
