31458-66TA Prestolite Style Starter Motors

This Protorque reproduction of the classic Prestolite long type starter motor is built to high standards using all new components. It is a direct replacement for OEM 31458-66TA and fits a wide range of Big Twin, FXR, Sportster, and Touring models. When replacing your starter, it is vital to confirm you have a Prestolite unit, as they are not interchangeable with Hitachi versions. This Prestolite style motor measures 70mm in diameter with a 173mm housing length and uses 1/4-20 UNC thru-bolts. If your original motor matches these specs, this high-quality reproduction will provide the dependable cranking power your Harley requires, offering a fresh start without the hassle of hunting down vintage parts.
