This stud kit comes with a warranty against breaking or stripping*. Using a stud/nut combo as opposed to a bolt to torque your head gives you more tensile strength, resistance to shearing, and elasticity by itself. Using our case hardened 304 stainless material instead of the inferior steel most OEM bolts are made out of combined with an allen head drive creates more torque, a better seal, less head gasket failures/changes, and a longer lasting motor. Put simply, these studs work better than OEM bolts. WAY BETTER. These are great for a stock motor and a must for any big bore/performance/hi comp application. Because no drilling or tapping is required, this kit is actually very close to the price of other head stud kits that do require irreversible drilling and tapping but at first may seem less expensive.
