rear end sag

I have Timbrens on my Ram 2500 towing 9000lbs with an 1800lb pin. Do I need them? No. Does it ride better with them? Yes. I don't understand some of the logic on here. Just because someone wants to improve the handling or ride of their truck some on here think it's because they don't have enough truck. OEM equipment or the lack of is one of the reasons many make changes. Aftermarket shocks, sway bars, tires, etc all make the truck handle/ride better. What's wrong with wanting to improve on something? If your truck came with a crappy stereo would you just leave it or put in a nicer one? If you truck came with tires that only gave you 30,000 of service would you by the same replacement? Same goes with truck suspensions. They all can be improved on.

It's kind of ironic in that some on here say if the trucks rated to tow it, then it should be good. And others say you need a bigger truck when you're maxed out.
