UMI Performance 1967 GM A-Body Handling Kit Stage 3 2in Drop - Red

ABF405-67-2-R

UMI’s Stage 3 kit works 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 improve camber gain. 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. Bilstein gas charged shocks control the entire package and provide great handling mixed with a comfortable ride. The kit is available in red or black powder coat and is 100% designed, tested, manufactured and raced out of our shop in Philipsburg, PA – USA.

Notes: An additional 1/4″ front end drop may occur on vehicles with full weight big block engines. Cars with lightweight LS engines may require spring trimming. You may safely trim the spring in 1/4 coil increments until desired ride height is achieved.

Key Features:

• Increased spindle height by 1/2” via tall upper ball joints for improved camber gain and a better contact patch. Works nicely in conjunction with lowering springs.
• Upper a-arms add caster for improved steering feel and straight line stability.
• Lower a-arms feature UMI-built Delrin bushings and accept standard springs or coilovers.
