FEATURES & BENEFITS • Replaceable Sub-Assemblies: For the extreme, repetitive track day enthusiast or racer, our high strength steel alloy spherical bearings (with a friction reducing, longevity increasing Teflon liner) outer and inner arm sub-assemblies can be replaced unlike the motorsports arms, in which case a new set of arms will need to be purchased if the spherical bearings are worn out. • Adjustable Suspension Geometry: Adjust dynamic camber values and roll center heights with our unique zinc plated steel bushings. • Solid Monoball Control Arm Ends: Offers better handling and a more responsive suspension over the factory one-piece rubber injected control arm by eliminating bushing deflection (also uses the same high strength steel alloy spherical bearing found in our control arm monoball kit). • 6061 Aerospace Grade Billet Aluminum Construction: Allows for a more uniform molecular structure at every point of the arm over the cast components providing a more durable and inherently stronger part. Manufacturing from billet aluminum rather than casting results in fewer impurities in the metal. • Anodized Aluminum Surfaces and Zinc Plated Steel Parts: Allows for better corrosion resistance against the elements.
