Description

Part #: ABF805-2-B

Since its introduction, UMI's Stage 3 kit has been the choice for GM A-body owners looking 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 " 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. We are especially proud to introduce our own ultra-premium springs built from CrSi wire and featuring 530 lb/in front and 130 lb/in linear rates. These carefully selected rates help your car split the difference between a comfortable ride and awesome handling. And what better to control the UMI springs than UMI's hot new SP series monotube shocks. The 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.
