How do I Pick the Right RoadActive Suspension Enhancement Kit for my 2018 Ford F-150

Question:

What factors determine whether to use the 3611Y kit or the HD, heavy duty kit?

We can get this figured out! The weight capacities stated in the description is the amount of weight that these springs will support. These will not add capacity to your payload or the amount you carry but instead take some of the force off of your factory suspension decreasing wear and tear on the system helping it to last longer. In my experience it also helps the handling characteristics of the vehicle by reducing the body roll of the truck.

The RoadActive Suspension Custom Leaf Spring Enhancement Kit part # RAS3611-Y have a weight capacity: 2,000 lbs the RoadActive Suspension Custom Leaf Spring Enhancement Kit - Heavy Duty part # RAS3611-YHD have a weight capacity: 3,000 lbs

Your F-150 has a payload capacity of 1125 lbs. up to 2311 lbs. depending on how it is equipped. If you were going to be on the high side of this say over 1900 lbs. I would use the RAS3611-YHD's if your going to be under that then the RAS3611-Y's will do the trick.

The cool thing about these is that you can adjust them according to the typical load you carry. If you aren't getting the result you desire you can tighten them up if they are a little too stiff for you you can loosen them up. I really like this system and have had a lot of good comments about them when working with customers. I've included a link to the video I did on them that further explains the system and how the adjustments are made.

I am also considering RAS upgrade for towing my 25 ft airstream behind my 2028 F150 4wd. I upgraded all 4 shocks to Bilstein 5100s. Now sag in rear more pronounced and porpoising notable as well. Trailer to give wt listed at 780lbs + three adults, dog gear...Standard or HD? RAS over Airlift 5000 bags?

If you have more sag and can feel more proposing then you might want to go with the HD version of the RAS if that's in fact the suspension enhancement system you decide to go with. Air bags are ultimately better than pretty much any other suspension enhancement out there (aside from maintenance) because it allows you to adjust the amount of support you need on the fly. For example, to adjust the tension of the RAS takes more work than just airing up or removing some air from the air bags.
