With a main bolt style that’s a reliable 2-bolt, they’re designed to keep your engine securely held together under pressure. Now, let’s talk about the fastener style. We're looking at good old-fashioned bolts here, which means you can easily get a grip with a hex head. No fancy stuff, just straightforward reliability. And while this kit doesn’t come with nuts (so make sure you've got those on hand), it does include washers, which is a nice touch for ensuring a snug fit.
