Suspension Enhancement Recommendation for 2015 Ford F-350 Dually

Updated 07/14/2025 | Published 05/31/2025

Question:

I have a 2015 F350 DRW 4x4 with upgraded front and rear suspension from the factory. With our current travel trailer there is a push-pull occuring that I believe can be remedied with suspension help. I am looking at the SSF-111-40 and SSR-139-40-2. Will these provide the suspension leveling that I am looking for? I did not have this issue with our 5th wheel. Thank You, Ross

Hey Ross, I am sure we have something that will help with the towing problem you mentioned but what exactly do you mean by upgraded suspension from the factory? If it's standard Ford suspension that the truck came with what I would recommend is actually the Roadactive Suspension kit part # RAS3611-SHD as this is by far the best suspension enhancement for your truck that will allow the truck to sit level and actually improves ride quality and handling loaded and unloaded which is basically unheard of.

Hello Jameson. I had the extra leaf added to the rear (prevent sagging under load) and stiffer springs in the front when I ordered the truck. The truck dropped less than an inch when our 14,500 lb 5th wheel was hooked up. This is not a leveling problem. We have the level bars with the travel trailer (9800 lb), no issue with leveling here either. This is more of 'rocking' feeling with the load being at the rear and not over the wheels, where an improved bump stop would improve the ride smoothness. Thanks, Ross

@RossH I see what you mean. Yeah the part# SSR-139-40-2 that fits the rear suspension would work great as well as the front part # SSF-111-40. This will give you additional support. You aren't using a weight distribution system are you?

@JamesonC Yes, we use a weight distribution unit. Thanks, Ross
