UMI’s Stage 3 kit is designed to achieve great street manners combined with Pro-Touring handling capability. Simply click and enjoy the performance. Up front you’ll find Delrin lower a-arm bushings for precise steering along with ½” taller upper ball joints to plant that tires contact patch. Out back they include their popular Roto-Joints and an adjustable length upper control arm so the axle can articulate nicely after you’ve perfected the driveline angle. Sway bars are UMI’s tried and true 1-1/4” front and 1” rear for a great front to rear handling balance. UMI’s new monotube gas shocks help to control the new premium lowering springs.
