    Product Description

    If your Volvo has been fitted with aftermarket lighting equipment, a high powered stereo or other electrical accessories, your charging system may not be up to the task. We offer an adjustable voltage regulator that will allow you to preset the operating voltage of the charging system and keep the system voltage stable. This can help in two ways; you’re able to adjust the voltage higher than normal to help your lights stay bright while using heater, wipers, etc., and you can also prevent voltage spikes after startup (which can lead to blown bulbs).

    Directly compatible with all B18, B20 & early B21 applications that have were fitted with Bosch alternators from the factory or that have been converted to Bosch alternators.

    Potential Product Fitment Issues

    About Aftermarket

    Aftermarket parts are a reasonably priced and good alternative to OE products. We often supply aftermarket products in place of OE parts that are no longer available as well. 

    Some items will be better than stock or considered an upgrade from the OE design in the aftermarket brand. 

    Other items will work as a less expensive alternative to stock. 

    We will not sell a product that we do not believe in, so rest assured you are fine with the aftermarket brand in most applications!

    If you have any questions, contact our customer service team to advise on the best aftermarket products for your Volvo.
