Spacer and Adjustment for Use with RAS Spring kit for 2015 Ford F-150

Question:

With the RAS set at 40, how much should I use on the front to level the truck. I tow a travel trailer with 720 lbs on the tongue Thanks

720 lbs of tongue weight is a solid amount for a 2015 Ford F-150 so going with the 40 percent spacer on the # RAS3611-Y that you mentioned would be the way to go to get the support needed for leveling the truck when towing. Beyond that though you are going to have to use some trial and error to further set the tension needed. It won't take long or be overly difficult but the amount of further adjustment can only be determined by you once you are all set up and ready to tow.

If you check out the attached review video link you can see more info on the install and setup process.

What is the difference between the RAS 3611B from the RAS 3611Y? From what I have read I must use the RAS 3611Y on my 2015 Ford F150 Platinum 4X4 pickup. I read a comment where someone with a 2018 F 150 4X4 had purchased the RAS 3611B and had to exchange it for the RAS 3611Y because the B would not fit the 4X4. So what is the difference?

For your Ford F-150 4x4 the correct RAS system is indeed part # RAS3611-Y. The difference between the two setups specifically has to do with the drivetrain on the truck and how they actually attach, which is why the part # RAS3611-B, which is designed for 2WD models, wouldn't fit your truck.
