The kingpin is the large bolt running through the center of the hanger and baseplate, connecting the two. The kingpin can be tightened or loosened against the bushings to allow for increased or decreased turning ability. This is done by adjusting the kingpin nut above the washer that also secures the kingpin in place. Shown tool adjusting nut. The washer prevents damage to the roadside bushing while also effecting the characteristics of the ride by control the of the bushing’s distortion when the hanger turns.” Close up of washer. Atlas Trucks come stock with a flat washer which doesn’t restrict the bushing and allows for increased turning ability when compared to traditional cupped bushing washers. This washer is power-coated, stainless steel and custom made to a 2.0mm thickness to achieve proper bushing compression.”
o Animate text “Tapered Kingpin”
o “A great truck requires a unique combination of kingpin qualities. The kingpin should be removable for maintenance and can’t have any slop between the kingpin and the bore hole in the base plate. Movement in the kingpin equals a sloppy low tech ride. Conventional truck designs either have driven kingpins or simple bolts, both of which fail to achieve the kind of performance Atlas thinks riders need and demand. In the pursuit of a removable kingpin with zero slop, Atlas had to break the mold of traditional kingpin design. Atlas Trucks have a high-strength heat treated kingpin that is custom made to taper at a 1:20 ratio to fit the tapered baseplate borehole, one of the unique Atlas patent pending design features. This ensures that as the kingpin nut is tightened the kingpin will be pulled up into the tapered bore hole to deliver a self-centering, zero tolerance precision fit. This provides secure support of the kingpin along its entire length so that the kingpin and baseplate act as one unit instead of two separate parts. As a result, you won’t feel the slop and rock of the kingpin that is present in many other trucks.
