Product Overview

Skunk2 has done it again. While others are busy imitating our LCA’s, Skunk2 engineers have spent years of extensive R & D to revolutionize a product that was once thought to be dialed in. The Ultra Series LCA’s are based off of the same technology the company’s been using in its own race cars for 20 years. Skunk2’s Rear Lower Control Arms are direct replacements, maintain OEM suspension geometry, and are ideal for street and race applications. 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. Accurate suspension geometry is maintained under the most aggressive driving conditions using high load steel spherical bearings on the trailing arm side and tuned durometer elastomeric bushings for the sub frame side of the LCA. Delrin bushings are utilized at the shock mounting position for their low friction and minimal deflection for unparalleled dynamic shock control. Using this select combination of bushings allows the most comfort and control under any driving conditions. For hardcore race level handling, we have also added the option to replace the sub frame side elastomeric bushing with a high load steel spherical bushing for a no-nonsense track car. The bushing change can be done in minutes with basic tools. Properly designed suspension components must be strong and functional first and aesthetically pleasing second. Skunk2’s Rear Lower Control Arms are both. For maximum suspension performance, Skunk2 Rear Lower Control Arms are best complemented with Skunk2 Rear Camber Kits, Lower Arm Bars, and Strut Tower Bars. * Forged 7075-T6 billet Aluminum * CNC machined to a precise fit and finish * 19% lighter than previous Skunk2 LCA’s * 44% lighter than OEM arms * 27% stronger than previous Skunk2 LCA’s * Spherical Bearing option to maintain accurate suspension geometry under aggressive driving * Tuned durometer Elastomeric bushings to dampen out harshness * Delrin shock bushings for low friction w/minimal deflection and dynamic shock control
