UMI Performance 1968-1972 GM A-Body Handling Package, 2" Lowering- Stage 1.5 - ABF815-2-B
UMI’s Stage 1.5 kit is the simple way to dramatically improve the handling and performance of your muscle car. We start with our original Stage 1 kit and take it to the next level by adding UMI’s new race-worthy rebound adjustable monotube shocks. The 20-click adjustment range covers street cruising, corner carving and even autocross or road course use. The Stage 1.5 kit also tunes up the camber curve by including ½” taller than stock upper ball joints that easily bolt to factory and most aftermarket a-arms. High performance lowering springs feature medium stiffness to control body movement and reduce floating while still providing a comfortable, sporty ride. The UMI rebound adjustable monotube shocks feature a large diameter piston and nitrogen charge to dampen bumps and provide a crisp feel without being harsh. The shock is built with heavy-duty mounts to ensure durability and fits in the stock location. They are easily adjustable with an external adjustment knob – no tools required. Stage 1.5 balances out with our tried and true 1.250” front sway bar and 1” rear sway bars reducing body roll and providing excellent chassis balance when handling at the limit. Every component in this kit, as with all UMI products, is Made in USA.
UMI Performance bump steer kits relocate the outer tie rod pivot point which results in decreased toe change during wheel travel. Standard kits include sleeves, rod ends, jam nuts and high quality, direct fit tapered studs. Race kits require drilling of the spindle and include heavy duty 5/8 bolts. Race kits are recommended for autocross and road race applications while standard kits are indicated for street/strip use.
