Upgrading the UCA (upper control arm) is a must when leveling or lifting your front end by 2-3”. Our meticulously designed UCA's correct your geometry for the ultimate ride. Specifications Uniball (PTFE Kevlar reinforced) bearing completely sealed for long service life Designed to maintain proper wheel alignment for 1.5in - 3in lift to prevent tire wear Custom-plated 14mm uniball through-bolt (equal in strength to a 12-point bolt) safely clamps the entire outboard bearing assembly directly to the upright - less chance of failure than 2-piece designs Allows full lock-to-lock tire clearance throughout the suspension travel Each inner rod-end has two bolts per side clamp for safety Each rod-end bolt has a nylock nut - no threaded holes to strip The inner rod-end clamps are fully radiuses inside and out - which means no sharp corners that might cause stress cracks FEA analyzed for 10,000-pound side impact loads Finished in Type II Anodize Product Highlights American made CNC precision machined and anodized in California Aerospace grade material Crafted from aerospace 6061-T6 Aluminum Completely sealed uniball Only we offer a billet UCA that fully seals the uniball, prolonging the life of the fastest wearing component. By keeping kevlar reinforcement PTFE liner free of debris and grime, its life is prolonged. CAD Designed and FEA Analyzed Using 3D scan data, we are able to reverse engineer the geometry and optimize it for lift. The geometry is configured for balanced comfort and performance both on and off road. Various versions of prototypes are made, installed, and analyzed to ensure correction of camber, caster and reduced bump steer. Machining Details Large chamfer at inner radius increases clearance for the coil spring at full suspension droop.
