The legendary V-twin is the centerpiece of your Harley Davidson motorcycle. It is what gives you the power for great rides, and it should perform as designed. However, if the miles have stacked up too high and the time has come to replace some of its major parts, including the block, or if you are planning a custom engine build, then the aftermarket is here to offer you a plethora of choices. Engine blocks and components offered are supplied by such manufacturing companies as S&S Cycle, Eastern Performance, and JIMS, designed for a variety of applications.

We have blocks that will fit right in without you having to modify your stock frame and chassis. These blocks are compatible with factory-style oil pumps, flywheels, gear covers, alternators, and plenty of other parts, while including bearings and headbolts. Some of the most durable and robust grades of metals and alloys are used in their manufacture, in order for them to be able to serve you reliably mile after mile. Harley Davidson motorcycle engine blocks that we carry are perfect for a variety of custom applications so you can tweak your machine with confidence!
