When you're undertaking cylinder head maintenance or replacement on a Paccar MX13 engine (model years 2013–2024), the head bolts you choose aren’t just “hardware”—they’re mission-critical fasteners that help maintain engine integrity. The OEM head bolts, part number 2301199PE, are engineered to precise specifications for strength, torque characteristics, and durability. Using subpar or incorrect bolts can lead to leaking gaskets, head warpage, or catastrophic engine damage.
