The Ultra Series Lower Control Arm offers the hardcore racer and discerning enthusiast, the very best of the best. In a market full of “Me Too” Product, and recycled, annealed lower control arms, we took the Lower Control Arm back to the drawing board. Often not used due to the higher cost, we chose 7075-T6 because of its exceptional strength to weight ratio and fatigue strength. With an ultimate tensile strength of over 78,000 PSI, and fatigue strength of 23,000 psi for 500 million cycles – This is the perfect material for our game changing Ultra LCA’s. The result of our hard work is a 7075-T6 Forged Aluminum LCA, that is 19% lighter and 27% stronger than our previous generation of LCA’s.
