Customer Questions & Answers

We will respond with an answer ASAP.

I have a f350 super duty 2015 with camper / towing package. Pulling a 40' raptor toy hauler. My rear end goes down about 3". Will the hellwig 3511-25301 stop this from happening? and how will it effect my ride?
Yes, these will definitely help. They should eliminate the sagging or at least minimize it. These helper springs are adjustable (you can tighten the ubolts as much or little as you like), towing a large trailer you will likely want them on the tighter side when towing. This will make your ride stiffer, especially when not towing, but you can adjust when they are not needed to the point they are not noticeable.
