Product Details

This Arrowhead starter motor features an 18-spline design, specifically built to meet or exceed the original manufacturer's specifications for your Harley-Davidson motorcycle. When you're looking to replace a worn-out starter, getting one that performs just like the original is key to ensuring your bike fires up reliably every time.

Arrowhead uses well-built components throughout this starter, which translates to more starting torque. This means the engine cranks over with more authority, especially important in colder weather or if your engine has higher compression. The design also aims for an extended life, so you can count on it for many seasons of riding. Being 100% OEM interchangeable means it's made to fit directly into your existing starter mounting location without any modifications, simplifying the installation process.

When installing a new starter, it's always a good idea to check the condition of your battery and cables. A strong battery and clean connections are crucial for any starter to perform its best. This Arrowhead starter is designed to work seamlessly with your motorcycle's 12-volt electrical system.
