UMI’s Stage 3 kit is designed to achieve great street manners combined with Pro-Touring handling capability. 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 we include our 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. Koni off-car rebound adjustable shocks complete the package. The Stage 3 kit is available in beautiful red or black powder coat and is 100% designed, tested, manufactured and raced out of our shop in Philipsburg, PA – USA.
Spring notes: Springs are intended for the Chevrolet small block engine. Lightweight LS may require trimming. An additional 1/4″ front end drop may occur with a full weight big block. Springs are designed to sit level, however due to varying weights and preferences, occasional trimming may be required.
