300 Series WOSP Alternators
The WOSP 300 Series represents our latest-generation alternator technology, designed for maximum efficiency and performance. These advanced units use square wire ‘hairpin’ (segment conductor) stators, delivering exceptional current density and allowing much higher output compared to traditional designs.

Each alternator case is precision-machined in-house from billet aluminium, ensuring strength, durability, and a perfect fit. The result is a range of plug-and-play alternators built to outperform standard OEM units while maintaining easy installation.

Key Features
