Main Studs

What are main studs?

Main studs secure the crankshaft. Main studs add longevity to your engine block. With a main stud, you won’t have tension on the internal studs inside the main blocks. Main stud kits also give more accurate torque reading. 

When it comes to needing a main stud kit, It depends on the strength of your engine build. They’re more widely known to be better because they’re less likely to twist during torque, leading to more consistent torque loading.
