Tremendous front grip and a host of features can be yours with UMI’s complete front end Grip Kit. The included a-arm kit enables 10 degrees caster while maintaining standard track width and wheelbase. Lower a-arms are assembled with tall lower ball joints to optimize roll center, camber gain, and center of gravity. Lower a-arms feature Delrin bushings for smooth travel and bind free performance. The new lower a-arm works in conjunction with the included adjustable upper arm which features minimum shim adjustability, Proforged ball joints, and super smooth Teflon lined rod ends. The front sway bar attaches using UMI’s swivel style end link design and double shear mounting system. The included Viking Crusader coilover shocks mount to the lower a-arm in double shear quick change brackets. The lower shock mount is removable to allow spring and shock changes at the track. UMI’s kit features Viking Crusader shocks with GF pro-touring valving (high rebound tie down for road race and auto-x) and a true 2-1/2” racing coilover. The upper stud mount fits in factory location while the lower is optimized to fit UMI’s 3057-1 coilover lower a-arm.  Some grinding is required for installation in the upper frame spring bucket.  Other spring rates and valve codes are available. Battle tested on the iconic UMI Green Machine. Kit is available in UMI red or black powder coat. 100% designed, manufactured and raced with pride in the USA.

Performance note: UMI recommends adding the P/N 3060-1 bump steer kit for optimal performance.
