SumoSprings for 2026 Ford F-150 FX4 Towing Trailer
Updated 09/17/2026 | Published 09/12/2026
Question:
Just bought a 2026 F150 FX4 and want to level out with a 3 inch lift, in addition add on sumosprings for occasional rv trailer pulling. Question 1: do you have spacers, and control arms to lift the front ? 2: which sumospring set should I get for my rv load of 4500 gross weight.
asked by: Johnny M
Expert Reply:
Hi Johnny! We don't carry the front spacers and control arms needed to give your 2026 Ford F-150 a 3" lift. Also, adding a lift will affect the fit of the SumoSprings since they are designed around the factory suspension height.
If you leave the rear suspension at the factory height, I recommend the SumoSprings Solo Custom Helper Springs # SS88UV. These have a 1,500 lb capacity which will be more than enough for a 4,500 lb trailer. They will help support the added tongue weight, along with whatever you're hauling, without having a negative impact on unloaded ride quality.
What travel trailer are you towing with your F-150?

I would recommend just a level kit for the front and 35’s will fit. Any bigger and you will struggle towing anything. I put the Sumo’s on the back of mine (front leveling kit only) and it’s perfect. I have a 16’ enclosed trailer I carry 4 dirt bikes in and it works great. Gives it just enough support so the back isn’t squatted.
