[Quad T]

I tried to do some searching, but I'm just not using the right key words I guess.

I'm looking for the suggested product from the brain trust here.

My Titan is a Big Tow, and my load is no more than 5,000 pounds and I have achieved a good tongue weight based upon both weight measurements and the general handling feel.

The pic in my sig may sort of show it, but I have a very slight drop in the back down from level. I'm looking for a product that will give my rear springs a bit more strength/help so when I'm towing the back end of the truck is not dropped. I do not need much of a height increase, just 1" I think would make a big difference. Keep in mind I don't want to add something that will just make the backend solid as a rock and ruin the ride when I'm not towing.

Suggestions?

Thanks!
