**USPS First Class Shipping Does NOT Include Insurance or Signature Confirmation**are direct replacements that greatly improve OEM suspension geometry by increasing freedom of motion on multiple axes simultaneously and eliminating suspension bind. Spherical Bearing Front Lower Control Arms offer the hardcore racer and discerning enthusiast, the very best of the best. Skunk2 uses brand new direct replacement cores rather than beat up used ones, saving you headaches associated with getting a used set that is potentially bent or damaged. Accurate suspension geometry is maintained under the most aggressive driving conditions using high load steel spherical bearings that are retained in the lower control arm with precision machined bearing sleeves that have been press-fit and TIG welded for redundancy. Each spherical bearing is locked into the sleeves with removable Spirolox, giving you the ability to service or replace when needed.
