Description

The Kingpin Machine EF Civic/DA Integra front radius rod spherical bearing set was originally designed (over a decade ago) to overcome the deficiencies of products available at that time while still remaining SCCA IT legal. That all started with proper bearing selection. What causes premature bearing wear and play in this application is high axial loads. Essentially, under acceleration and especially under braking the load is attempting to push the spherical bearing ball out of the bearing race. Our solution was to use a wider, aerospace quality bearing with vastly higher axial load ratings and a much higher end PTFE liner than the competition used.

We use 4140 HT (Heat Treated) steel for the bearing housing as well as the rear bolt plate. 303 Stainless Steel is utilized for the four bearing spacers and 5 mm shims are included to help dial in caster and account for a less than straight chassis. The bearing housing design incorporates a shoulder at one end of the inside diameter to provide a positive stop when pressing in bearings and eliminate a failure point. Bearings are then blueprinted/lightly press fit into the housing for near perfect stiction, retaining compound is used to augment the press fit and finally a c-clip at one end provides triple redundancy.
