These monoball top mounts replace the compliant factory rubber bushing with a precision Teflon-lined spherical bearing for quicker steering and shock response, and increased suspension precision resulting in better handling. The spherical bearing is made to Tarret's 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, lightweight, 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 tend to cause annoying rattling and possible failure.

These domed style are designed to replace the OEM mount and is compatible with any strut designed for use with the OEM mount.  This would include Bilstein among others.  Contact us for KW V3 fitment. 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.
