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
- Advanced hairpin stator technology for superior efficiency
- Precision billet housings manufactured in the UK
- Wide range of direct-fit, plug-and-play applications
