An ATV depends on its engine. The engine depends on the crankshaft. The crankshaft depends on the main bearing. That’s why even something as small and seemingly insignificant as the crank bearing is an essential component of your quad. Fortunately, when it’s time to replace your machine’s crankshaft bearing, you can find what you need at Rocky Mountain ATV/MC.
We carry crank bearings from two major brands in the industry: All Balls and Hot Rods. These are designed to be excellent replacements that will give your quad’s crankshaft new life. (Of course, if you’d rather stick to stock, we’ve got those too. Just head over to the OEM section of our website.)
The crankshaft bearing is often known as the main bearing. Why does it sport a name of such significance? The crankshaft is directly connected to the piston. It helps the crank convert the up-and-down motion into rotational energy – exactly what your quad needs to turn those wheels and go. Its importance cannot be understated. So when your ATV needs a new crankshaft bearing, replace it.
