Spherical Bearings with aluminum hats, designed for the ND Ohlins DFV's (which do not come with top hats). Included in the kit are front and rear top hats, for the ND Ohlins DFV. These top hats remove hysteresis caused by rubber bushings, and add no NVH! Since Ohlins does not include top hats for the ND kits, we have made them available to add on as an option! These are the same top hats included in our FPSport Ohlins coilovers.
