These did a great job on my Raptor. Stock suspension does not like heavy loads and feels unstable. Adding these made my trip from Alaska towing an 18 foot trailer feel much more stable. They are a little firm for daily driving without a load on the truck

I got these after dealing with a lot of rear sag in my 2015 F-150 (due to not having a tow package) when pulling our camper (~6000lbs). I chose these over airbags because I wanted to install them and forget about them. I am very happy with them as it helped keep the rear of the truck sagging to almost none for what I have to tow. It did take out a bit of the smooth ride when I don't have a load in the truck bed or am towing something, but it is not bad at all.... great product all around and would def buy again!

Fits my 2017 f 150 perfectly. Easy to install and stabilized the truck when towing our 7200# travel trailer. Count this as two thumbs up!

Great product. Installation was super easy and it took about 1/2 an hour. These springs stabilize and smooth the ride while towing.

I installed on my 2010 F 150 Super Crew in anticipation of getting a small fifth wheel trailer. The bottom of the springs are about 1/3" above the axle with no cargo in the truck and very little gas. I assume they will be resting on the axle after I reinstall the spare tire, install the fifth wheel rail kit and have more gas in the tank.Update: 04/10/2018After over 12.000 miles towing a small fiberglass Fifth Wheel Trailer .(Escape 5.0 TA) the SumoSprings are working very well. When I lower the trailer onto the Anderson Hitch in the bed of the truck the truck settles about an inch an a half but is still level. I'm very glad to be using these. My 2010 F 150 already had 116,000 miles on it before i got a trailer to tow.
