Head Stud Kit built for 2008 Mitsubishi EVO X Designed to provide reliable cylinder head to block clamping for compression and forcedinduction applications, this head stud kit improves sealing and alignment where it matters most. Key benefits Improved sealing and alignment: Precision manufacturing produces straighter studs so cylinder heads and gaskets align and seat more easily during installation. Higher fatigue strength: Studs are thread rolled after heat treatment, resulting in roughly ten times greater fatigue resistance compared to studs threaded before heat treatment. Consistent clamping: Heattreated material and controlled stretch reduce variability in clamp load, helping to minimize head gasket leakage under repeated thermal and boost cycles. Built for boosted and compression engines: Ideal for turbocharged, supercharged, nitrousassisted, or compression street and race engines where headtoblock sealing is critical. Important features Material: 8740 alloy, heattreated to a tensile strength of 200,000 psi. Precision finish: Centerless ground after heat for exceptional straightness and concentricity. Thread treatment: Threads rolled after heat for strength and durability. Undercut short studs: Shorter studs are specially undercut to more evenly equalize stretch and improve clamping consistency where applicable. Compatibility: Built for 2008 Mitsubishi EVO X applications requiring strength head studs. Practical use scenarios boost track build: Use this kit when upgrading a turbocharged EVO X for higher boost and power to improve head sealing under sustained boost. Nitrous or supercharger setup: Install during forcedinduction or nitrous upgrades where cylinder pressures increase and head gasket integrity is a concern. compression engine build: Fit this kit when converting to higher compression pistons for improved reliability under increased combustion pressures. Package dimensions 16.51 cm L x 10.16 cm W x 5.334 cm H What this kit solves Prevents misalignment and uneven clamping caused by inferior studs. Reduces the likelihood of head gasket failure in stress engine builds. Provides durable, repeatable clamping force for engines that see frequent thermal cycling and cylinder pressures. Notes Confirm fitment for the 2008 Mitsubishi EVO X before installation. Install and torque according to engine builder or head gasket manufacturer specifications to achieve intended results.
