Recommended RAS Leaf Spring Enhancement Kit for 2018 Ford F150 4WD Towing 37 Foot Travel Trailer

Question:

What information do I need to determine which kit to purchase for my 2018 Ford F150 with max tow package? It is 4WD and I tow a 37foot travel trailer. Just want to make sure I get the right unit.

RoadActive Suspension offers two different kits for the 2018 Ford F150 4WD, part # RAS3611-Y which offers up to 2000 lbs of support and the # RAS3611-YHD that you'd looked at, which offers up to 3000 lbs of support.

If you're simply looking to support the trailer's tongue weight, I'd recommend going with the lower-rated # RAS3611-Y unless you haul a lot of heavy cargo in the truck bed while towing. If that's the case, the higher rated # RAS3611-YHD would work better.

I've linked to a demonstration video that explains how the RAS system works.
