Description

Engineered for Endurance. Crafted from high-strength DOM (Drawn Over Mandrel) seamless steel tubing, this UMI Performance Road Race K-Member is built to endure the harshest driving conditions. Whether you're tearing through corners on the track or pushing limits on the street, this reinforced design delivers superior rigidity, long-term durability, and precise suspension support exactly where you need it. Includes UMI's 5-hole anti-slide retention system. Welded-in LS1 motor mounts. Offers generous clearance for headers, turbo piping, and custom exhaust routing. Approximately 22 pounds lighter than the factory unit. 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. Rear main cross tube lowered for oil pan protection and coverage. Uses integrated motor mounts.
