rear end sag

I just bought a 2005, trd off road, double cab, short bed tacoma with 54000 miles on it. the guy I bought it from put a leveling kit on it, which I like a lot because its not too big, but yet it is not stock. but the back end is lower than the front. Is there something I can do to raise the back end so its more level without spending a bunch of money? I didn't notice how low the back end was until I drove it around for a while. And right now because I live in Rexburg Idaho I keep 400 lbs of rock salt in the back so that it handles better on the ice. I took all the salt out and drove around to see if it was just the salt causing it to sag so badly. But it still isn't as level as I would like it to be. One of my friends suggested airbag suspension, but like I said, I don't want to spend a bunch of money. If you could give me some suggestions, it would be much appreciated. thanks!

 

all pro has good deals on leafsprings

 

The typical thing to do in this situation would be to add an Add-A-Leaf to your rear leaf pack. It's pretty easy and they're available in 1.5 and 2" heights.

 

Does the leveling kit include anything in the rear or is the rear stock?

 

I am pretty sure the rear is stock. but I am not positive.

 

Add a leaf to the rear if you use it as a truck or off road, or block lift if it's a grocery getter.

 

Thanks everyone! i will get on that asap!

 

EEp.. I hate the add a leafs. Very harsh in my limited experience. Like air bags, but probably not for a lift.
