Aftermarket head studs for the 2006-2007 GM 6.6L Duramax LBZ are crucial for those looking to upgrade and modify their engine with high-compression or turbochargers, both of which experience extremely high internal cylinder pressures. We commonly see upgraded head studs and main studs installed in automotive racing engines as they are proven to be much more durable over the OEM components. Additionally, a new set of head studs is especially useful for cylinder head installation while providing more accurate and consistent torque loading for your rig.
