Show original supplier description
The UMI Performance ABF805 Stage 3 Handling Package is meticulously engineered to transform your 1968-1972 GM A-Body's driving dynamics, delivering exceptional street manners and Pro-Touring handling capabilities. This comprehensive kit features precision-crafted components including tubular lower and upper control arms equipped with UMI-built Delrin bushings for razor-sharp steering response. Experience balanced handling with the included 1-1/4” front and 1” rear sway bars, CNC bent from 4140 steel for optimal performance. The package also incorporates premium Bilstein gas-charged shocks, providing unmatched control and comfort across various road surfaces. UMI springs with linear rates (530 lb/in front, 130 lb/in rear) ensure consistent handling characteristics. The kit is available in red or black powder coat finishes and includes Grade 8 hardware for secure installation. It is proudly designed, tested, manufactured, and raced in Philipsburg, PA, USA. Important considerations include that vehicles equipped with full-weight big block engines may experience an additional 1/4" drop in front end height. Lightweight LS engines might require trimming springs in 1/4 coil increments to achieve the desired ride height. The comprehensive kit components include tubular lower and upper a-arms with Delrin bushings, heavy-duty sway bars, tubular rear control arms with Roto-Joint technology, tubular frame braces, replacement rear end housing bushings, Grade 8 hardware kits, lowering springs, and premium Bilstein gas-charged shocks.
