After you have upgraded your suspension and put on taller tires, don’t overlook the driveline components that will need to be upgraded. You may need to change your ring and pinion gear ratio to adjust for the larger tires. We offer an extensive line of high-quality products from Alloy USA, including forged U-joints and 4340 chromoly axle shafts. Alloy USA uses upgraded splining technology to create stronger splines compared to traditionally cut splines. Before you break down on the trail, upgrade your axle and differential components!
