The caster angle of a Ford Super Duty can vary depending on the specific model and suspension setup. However, the caster angle generally falls within a range of 1.5 to 4.1 degrees. It is important to note that installing a suspension lift or leveling kit can cause a reduction in the steering caster angle, which may result in steering instability. To correct this issue, some aftermarket kits, such as the BD Cam Caster Adjusting Kit, can be installed on the radius control arms to increase the caster angle and improve stability [[9]].

How do you adjust the caster angle?
One way to adjust caster is with an adjustable arm. In the case of a MacPherson strut system this can be in the form of an adjustable tension rod that holds the lower arm forwards or backwards in the wheel arch. The screw can be adjusted to move the wheel forwards or backwards adjusting the caster angle.
What is the normal caster angle?
between 3 – 5°
Positive caster angles run between 3 – 5° on modern vehicles. This gives a good mix of highway stability and steering feel. For a more performance oriented setup on a MacPherson strut you can add a degree or two to have more favorable camber gain at high steering angles.
Can caster angle be adjusted?
One way to adjust caster is with an adjustable arm. In the case of a MacPherson strut system this can be in the form of an adjustable tension rod that holds the lower arm forwards or backwards in the wheel arch. The screw can be adjusted to move the wheel forwards or backwards adjusting the caster angle.
What kind of caster do most vehicles have?
Most modern vehicles run a certain amount of positive caster with the steering axis tilted rearward toward the driver. The steering axis is the imaginary vertical line that runs through the center of the tire and wheel assembly from the ground toward the steering wheel or away from it.
What is caster angle on truck?
Caster is the angle that identifies the forward or backward slope of a line that is drawn through the upper and lower steering pivot points. It does not affect tire wear, but caster does have an influence on the directional control of the steering.
What happens with too little caster angle?
If you don’t have enough positive caster (forks too little angle toward the front) the car will wander and feel unstable. If you have too much positive caster, the vehicle will be harder to turn. However, just like with camber, vehicle pull is not caused by too much or too little caster, but by side to side imbalance.
How do you find the caster angle?
Take a look of a number that is your caster angle. Now this keeps sitting at about 2 and 1/2 degrees. So we need to little bit more caster.
What degree should caster be?
A safe starting point for caster is 2 to 3 degrees of positive caster. Positive caster is achieved by either adding shims to the rear bolt or removing shims from the front attachment pointfor the upper control arm. This will probably affect camber, so you will want to check it again after modifying the caster.
Which is more important camber or caster?
Caster directly affects steering wheel speed and turn radius. Imagine pushing a dolly or riding a bike. It’s much easier with positive camber. If you draw your kingpin axis all the way down to the ground, and it hits the center of the tire at the same point it hits the ground, then you have zero scrub radius.
What is the downside of too much caster?
However, excessive positive caster in association with other alignment maladjustments can exacerbate a tire wear issue. For example, a tire wear pattern called feathering can result from a combination of too much caster with incorrect toe settings.
