Description:
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.
1.250” front sway bar for flat cornering, CNC bent from 4140. Balanced with 1” solid heat formed rear sway bar.
Bilstein gas charged shocks.
UMI springs feature ultra premium CrSi material with linear rates front and rear for consistent handling. (530 lb/in front, 130 lb/in rear).
Rear trailing arms feature Poly and Roto-Joints as well as adjustable uppers for setting pinion angle and rear lateral location.
Roto-Joints allow smooth articulation for improved handling and less bind.
