For the Blaster kit, we highly recommend the +6.0 inch kit because the stock Blaster is so narrow to begin with. The +6.0 kit also allows more room for using longer shocks if you purchase the Widening and Shock Conversion Kit.
Stock brake lines should be long enough to install either the +4.5” or the +6.0″ kit if you disconnect the intermediate brake line support on the a-arms to provide more slack in the lines. You may also need to disconnect and reroute the brake lines over the top frame tube to allow even more slack.
Diamond J Customs does sell brake lines if your Blaster has hydraulic disk brakes, and you would prefer to use extended-length stainless steel braided brake lines with your widening kit.
You can find more general information about our widening kits under the Front Widening Kits menu from the Home Page.
