Pro-Line has the ultimate rim solution for X-Maxx owners with these Impulse Pro-Loc rims. The Impulse features a ground breaking Bead-Loc design that allows users to change tires or foams when necessary without worrying about the tires coming out of the bead. Pro-Line’s proprietary Pro-Loc Technology brings this feature to life and creates an ultra-secure bond between Pro-Line’s Pro-Loc Tires and Pro-Line’s Impulse Pro-Loc rims. The reinforced Tire bead of Pro-Line’s Pro-Loc Tires fits into a uniquely shaped channel on the rim and the bead-loc screws actually pass through the tire rubber before being pinched by the outer bead-loc ring to create the maximum possible mounting security. The Impulse design is inspired by full-size off-road rims with a tough, blacked-out look and is manufactured at Pro-Line Headquarters in the USA out of extra thick, extremely durable material designed to take some serious abuse. The look of the Impulse Pro-Loc rim is finished off with the Stone Gray Bead-Loc Ring that will get your truck noticed wherever you go! If you want to take your X-MAXX to the next level of Performance and Durability get Pro-Line’s new Impulse Pro-Loc rims.
