The Team Durango DESC410R 4WD short course truck has lots of setup options in its arsenal, to dominate on the race track. Outer hinge-pin height is a setting which can help tune the truck to the track, and both front and rear hubs on the DESC410R have the option to change hinge-pin height in this way.
Moving from a high outer pin height – with the hinge pin in the upper hole – to a low one without changing any other settings would result in the car sitting lower, for example – so adjustments to the spring collars on the dampers might be needed to attain the correct ride height after alterations to the pivot are made.
On the rear of the DESC410R it’s as simple as deciding on low or high pin mounting, and mounting the hub in the desired location. On the front of the car however, the steering will foul the suspension and / or provide inconsistent steering performance due to a change in bump-steer – so you need to swap the steering knuckles from left to right side of the car when changing the hinge pin height to a different setting.

The kit default setup is to have the hinge pins in the low position front and rear. The steering knuckles have an off-set ball stud platform for the steering link and when moving from the low to the high hinge pin position you need to swap the knuckles between each side of the car (and swap the ball stud itself to keep it facing upwards).
The steering knuckles are marked for easy identification with small dimples on the outer face – this is to ensure you get the steering knuckles oriented correctly when using either the low (1 dimple at the bottom) or high (2 dimples at the bottom) hinge pin location. See the example below for a clearer explanation of the required setup in either hinge pin position.
In the example above – the outer hinge pins are shown at the same height but the hubs are in their low & high positions. The steering ball studs are relatively the same height as each other due to the off-set steering knuckles.
The rear hubs are a much simpler setup change, having just two holes. Just like the front end of the car – the change in outer hinge pin height will affect ride height and the shocks will need adjusting to compensate.
So – what does it do?
Lowering the outer hing pin height reduces chassis roll and the car will react quicker. Raising the outer hinge pin height will allow more chassis roll and slow the reactions of the car.
