UMI’s industry leading twin tube road-race k-member has gone to the next level. UMI’s road race k-member has been tested on auto-x and road courses across the east coast. Our new adjustment plates feature a bulletproof locking mechanism which provides the ultimate in alignment retention. Laser cut plates lock the lower a-arms into position for absolute confidence. Five positions of adjustment are available on the k-member in addition to the adjustment provided by the UMI lower arms. Our road race k-member also features additional bracing over and above the already tough UMI standard k-member. We recommend the road race set up when you want to dominate the auto-x course, road course or street.
