    Choosing engine parts

    A good engine rebuild starts with the parts that hold everything together. Replace main and rod bearings, rings and gaskets whenever the engine is apart, and measure clearances before you assemble.

    Head studs and head bolts do the same job but in different ways. Studs give more even clamping load and are a common choice on built or boosted engines, while bolts are fine for many stock rebuilds. Always follow the fastener maker's instructions for lubricant and torque, because those numbers are not the same as factory bolts.

    If you are adding a turbo, plan the supporting parts together: boost control, wastegate or blow-off valve, fuel and tuning. Camshafts should be picked for the whole combination, including compression, gearing and the RPM range you drive in.

    Brands we carry in this category include ARP, Comp Cams, King Engine Bearings, ACL, Turbosmart, Mishimoto and Eagle.

    Common questions

    Should I use head studs or head bolts?

    Either can work. Studs are a common upgrade for high-load engines, and head bolts are fine for many stock rebuilds. Check the part's application notes for your engine.

    How do I check that a part fits my engine?

    Use the vehicle selector at the top of this page to see only parts that fit your Year, Make and Model, then check the notes on the product page for engine, trim and position (front or rear). Engine size and block type matter, so compare them with your own before ordering.

    What is your return window?

    Returns are accepted within 60 days, unused and in the original packaging, and return shipping is free. See Shipping & Returns for the details.
