    Before you order: fitment and what to plan

    Engine bearings let the crankshaft and rods spin on a thin film of oil.

    Fitment notes

    • Engine: check the engine size listed against your vehicle's VIN or under-hood label.
    • Specs, lead time and warranty come from ACL and can change. The details above this guide are the latest we have.
