Next week I will be installing Bilstein 5100 on my 2021 5.0 4x4 supercrew cab. I love the stock height but at the same time I want the best height setting for the 5100 ride quality. So which setting do everyone recommends for the best ride quality?

 

Wouldn't you leave the rear at stock and set the front at 1.5 to level it out just right? Others chime in..

 

For now I'm looking for ride quality and I won't care about leveling or stock height. Does 1.5 will provide the best driving quality?

 

The Bilstein's are going to be a noticeable improvement in ride quality at the stock setting. I have had two sets (many years ago, not on an F150) and they are well worth it.

 

5100 rears are not height adjustable.

5100 fronts are height adjustable by choosing one of 3 spring-perch locations. That does nothing to alter the shock valving, nor does it alter the spring rate. Therefore, there is no difference in terms of damping or 'springing' at any ride height these shocks can accommodate.

If you choose the higher spring perch location (lift the front of the vehicle) you will slightly raise the vehicle CG and roll-center, and will transfer a slight amount of weight to the rear. IMO those differences will be imperceptible.

Bottom line, within the range of height adjustments available with the 5100's, there will be no perceptible difference in 'ride quality' between those settings. Choose the height that looks best to your eye without concern about optimizing or detracting from 'ride quality'.

FWIW, I installed mine at the stock front height and love 'em.

 

I went with the setting that DID NOT provide any leveling.

im happy with the ride. It is a truck after all.

 

Did 5100 in rear 2 weeks ago, does not change ride height, as expected, but good difference in ride. Had 5100 front done today to level and love the ride quality and look.

 

I just had the front done on my truck this week. I chose the 2-inch setting, and the truck looks great as it is now not nose down. Ride quality is better than stock. If you don't care about leveling out the front, then why not choose the 4600 which is not adjustable.

 

Is there a difference bw 4600 and 5100 in terms of quality and durability?

 

4600 will give a smoother ride, whereas the 5100 gives firmer and rougher unloaded ride. That said driving on the new ones feels much better to me.
