1978-1987 El Camino UMI Stage 3 Handling Package, 1 Inch Lowering Springs, Black GBF003-1-B

UMI's Stage 3 kit is designed to achieve great street manners combined with Pro-Touring handling capability. In this newest revision we've refined our parts list to provide the most common options in one convenient package. Simply click and enjoy the performance. Up front you'll find Delrin lower a-arm bushings for precise steering along with 1/2 inch taller upper ball joints to plant that tire's 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 inch front and 1 inch rear for a great front to rear handling balance. UMI's new monotube gas shocks help to control the new premium 1 inch lowering springs. 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.
