The compliant factory rubber bushing is replaced with a precision Teflon-lined spherical bearing for increased suspension rigidity, quicker steering response, and better handling. The spherical bearing is made to our specific specifications, and will not wear out and rattle like others on the market. The housing is CNC machined from 6061-T6 aluminum billet, providing high-strength, light weight, and a perfect match to the factory mounting surface. The spherical bearing is securely clamped into the billet housing. Other designs use a small retainer ring to trap the bearing in a bore, which could cause annoying rattling and possible failure. The spring load is distributed on the housing, not the monoball, for increased monoball life. These are the only upper mounts on the market that are fully compatible with all factory and aftermarket style upper spring seats.
