Perhaps the most crucial component in your vehicle is the crankshaft. The crankshaft lies at the heart of your motor and is responsible for spinning the pistons up and down to provide the power that propels your ride forward. If you have a damaged GMC Sierra crankshaft or are looking to do a complete motor rebuild, then you should seriously consider a brand new GMC Sierra crankshaft. Here at Andy's Auto Sport we have a great selection of GMC Sierra crankshafts for you to choose from. Whether you want an OEM replacement or a high-performance version, you are sure to find the perfect unit for your application in our extensive selection.

The crankshaft in your engine rotates at high speeds and undergoes intense heat that puts it at risk for wear and tear, and ultimately failure. If you are rebuilding your motor it is important to carefully examine your crankshaft for damage. If there are any scratches or gauges we highly recommend getting a new GMC Sierra crankshaft. A new crankshaft can also provide increased performance and strength to ensure vehicle longevity and give substantial power gains. When it comes to your engine do not cut corners. Make sure that you vehicle keeps running for years to come with a new crankshaft.

Q: What is a crankshaft? Why buy one?
A: The crankshaft is at the heart of your motor. It spins round and round driving the pistons up and down and directing power to the rest of the drivetrain. Over time your crankshaft can wear out at the bearing surfaces to the point where you will require an entirely new crank. Replacement crankshafts are available so that you can properly rebuild your motor and restore your vehicle’s performance. Stroker crankshafts are also available and feature a longer stroke for the connecting rods which effectively increases engine displacement and can drastically boost horsepower and torque. In addition to the crank itself there are also crank accessories that may need replacing such as woodruff keys, thrust washers, and crankshaft seals. We carry all of these components as well to ensure that you get the job done right the first time.
