Collection: Andrews

There are some names that engine builders just know – they don't need marketing, because the performance speaks for itself. Andrews is exactly like that. For more than half a century, Andrews Products has been manufacturing precision camshafts, transmission components, and internal engine parts for Harley-Davidson motorcycles. The brand's reputation is no accident: Andrews cams have been the most sought-after choice for generations when someone is serious about performance enhancement – whether it's a low-RPM, high-torque touring setup or a high-RPM, aggressive performance character. In our selection, you'll find Andrews camshafts with various lobe profiles and characteristics, from classic, balanced touring profiles to race-tuned, extreme-lift versions. In addition, Andrews transmission components are also available – gears, shafts, and related components – which are made with precise manufacturing and high-strength materials to reliably withstand heavy loads. Andrews products don't just deliver performance – they also add character. A well-chosen camshaft can give an engine a completely new personality: a different sound, a different torque curve, a different feel with every throttle twist. Whether it's part of an engine rebuild or the foundation of a serious performance upgrade project, you'll find the Andrews parts you need to give your engine the exact character you're looking for.
