PPE Mercury Head Stud Kit
The Power Performance Engineering head stud kit was designed in-house to replace the head bolts on all Mercury 2.5 Liter V6 2-stroke outboards manufactured between 1991 and 2005.
This replaces the OEM head bolts with high-strength studs and 12pt nuts to allow for more precise and increased torque specs with less potential damages to the threads in the block.
Our kit includes 24 heads studs and 24 nuts to replace the original 24 OEM bolts (SCREW - part number #10-98534).
We crafted these studs using an industry-leading thread rolling process, which is literally a metal forging process that forms threads into the mirror image of a roller die. The process is different from metal cutting, grinding, and chasing because it does not remove any metal from the workpiece. Instead, thread rolling uses hardened steel dies to make the base part and the threads harder and stronger.
