I have the F250 Lariat FX4 4X4 and am need of any info on what shocks to replace the Rancho's that are on it. It squats when my travel trailer is hooked up to it.It' a 30 ft trailer. Should have no problem. I have looked at the Bilstein and Pro Comp shocks but not sure. Any ideas?

 

Have you had a chance to check the combined gross vehicle weight of truck and trailer?
Some states have limitations on what a certain rated vehicle can legally pull? There are considerations regarding tongue weight of the trailer when hooked to the truck.
That is not my so called field of expertise and hopefully someone with the required knowledge will pitch in an help you here.

 

The weight of the trailer and its tongue weight matches the truck and the truck has no problem pulling it. When the trailer is hooked up and level the tail end of the truck has squatted down, not much but enough to see.Just want to know what rear shocks would help.

 

Shocks don't help with the squatting issue unless they are "COIL OVER" shocks. I would try a weight distributing hitch is you're not already using one. The other option would be to install a set or quality airbags. You could also use an "ADD A SPRING", or install a set of F-350 springs.

 

I have a set of airbags on my F350. Very helpful.
