Why Choose the LMA331-RALLYMINI?

• Square Wire Technology: Patented design allows for more copper in the same space, maximizing output while reducing heat
• Built for Extras: The perfect choice for cars running high-draw accessories like heated screens, electric cooling fans, and high-intensity spot lights.
• Idle Performance: Unlike standard alternators, this unit provides near-maximum power even at low RPM—crucial for night stages and slow-speed manoeuvring.
  
• Rally Tough: Features a reinforced casing and the same belt-retention pulley found on our race-spec components.
