Use underdrive pulleys for those applications that do not require large electrical loads. If large electrical current demands exist, we recommend going to an aftermarket alternator retrofit performed by a dependable shop, if using these pulleys and your lights are dim, increase your rpms at idle and consider a high amp alternator retrofit
