Crankshafts

Hot Rods Complete Crankshaft Assemblies Keep your rebuilds short and sweet by using quality components like the Hot Rods Complete Crankshaft Assembly. Hot Rods crankshafts are made from some of the highest quality forgings available, and thanks to an entire system of quality control checks and rechecks, these cranks meet or exceed OEM parameters. And Hot Rods tunes and trues their components to OEM specification for your bike, ATV, or UTV so you won’t have to do any guess work or tuning of your own. Each component is copper plated, case hardened, heat treated, CNC machined, and held to a tolerance measured in microns for the best fitment and friction reduction possible in a crankshaft. This package comes pre-assembled with connecting rod(s), top-end bearings, and crankshaft webs so you’ll be able to simply drop it in and keep moving on with your build.
