considerably more cranking power than original units, whilst drawing less current from the battery. The units are ideal for road competition applications, especially where engines have been tuned and adverse conditions require extra performance from the starter motor. All Powerlite starters are direct replacement for original units and require no modifications to the vehicle on which they are installed, as they work for both positive and negative polarity (Except the Slimeline Range). The compact lightweight units are often easier to install than the original unit and units are modified where necessary to aid fitment.
