Leaf Spring Enhancement for a 2021 Ford F-150 4wd Towing a 7,400 lb. 5th Wheel

Question

Question:

What suspension enhancement do you recommend for towing my fifth wheel 7400 lbs dry weight with my F 150 4wd? I had Summo springs on my 2016 f150 but not sure I want to use the axle for support this time around The RAS system Roadmaster seem like a better alternative. What say you?

Since your 2021 Ford F-150 is a 4wd you will want the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-Y, as this is the correct leaf spring enhancement for the 4wd models. This will be a great option for towing your 5th wheel. This all-in-one suspension system will improve stability, handling, and control while eliminating axle wrap, wheel hop, and bottoming out. It will also help to reduce dangerous sway and body roll while cornering and keeps your ride level when towing or hauling a heavy load. You will be happy with the # RAS3611-Y system.
