Although this isn’t strictly geometry, the bushing seat makes such a huge difference to the way a truck turns that it deserves to be included in this guide.
There are many different shapes and depths of bushing seat, but broadly speaking, it’s the depth you want to pay attention to.
The deeper or more “restrictive” the bushing seat, the more pressure there is on the bushing, and the less the truck will turn. You can compensate for this by running a softer bushing. Restrictive bushing seats moves the bushing more, which means that changing the duro of your bushings makes less of a difference.
The shallower or more “open” the bushing seat, the less pressure there is on the bushing, and the more the truck will turn. You can compensate for this by running a harder bushing. An open bushing seat lets the bushing do what it wants, which means that changing your duro of your bushings makes a much bigger difference.
We have two distinct bushing seat possibilities on our hangers:
- Choose Cold Forged Precision hangers for a very open bushing seat
- Choose Gravity Cast hangers for a more restrictive bushing seat
