Rear spring upgrade?

I have a 2014 trd off road double cab with manual transmission 42800 miles , i work in construction so i generally always have a small job box in the back of my tuck full of tools plus lots of times my back seat too, im sure its been discussed here millions of times but who can tell me about the rear spring upgrades and what to buy? Right now my truck is totally factory and im feeling like the back end is really sqatting under the weight of my tools.

 

If you want to just keep stock height, then I'd go with sumo springs. I have a tonneau cover on mine and those are heavy. Stuck some Sumos on it and back to ride height and will take more weight when needed. So far, been happy.

Others will say to get ride right air bags, but they can get holes and lose air

If looking to lift, then Mary @Headstrong can set you up.

 

If you're driving with this weight all the time and you're nose high, an AAL setup will probably bring you back to the stock raked look.

 

Add a leaf is best option and bang for buck.

Really any AAL will work. I would think a leaf pack is overkill for tools.
