Yeah dude im pretty sure theyd be fine. Itd be even more legit if you had some rancho 9000s or something and you could turn the shock up to nice and stiff when youre towing. like i said, theyre fine up untill you mess with taking a leaf out cause they obviously get softer, sag a little, and cant take a load as well...
how big of a load are you towing, the weight on the ball?
