Deaver stage 3 or dobinson super heavy duty leaf springs??

So I have a lifted Tacoma with the Ome heavy duty leaf pack in the back. They gave me 3 inches of lift but within six months it is already sagging an inch and a half down. So I need to change them up. Any weight on them and they sag bad.

if you had to go with a more heavy duty leaf pack, which one would you go for? Deaver stage 3 700-900 lbs or dobinson super heavy duty leaf pack up to 1,100 weight. I was told deaver is a 3inch leaf pack but dobinson not sure.
If you had to spend the money on a heavier leaf pack them the ome, what would you choose? Thanks guys

 

The dobinsons super heavy leaf pack will put you at around 3" without a super heavy load and sit more around 2-2.5 with the full payload of your truck in there. What do you have in the back of your truck? the dobinsons leaf pack is also less expensive by a few hundred and its a really good product.

 

The only thing I have on there is a truck cap. which I think weighs about 198 pounds. I do point between 500 and1100 pounds in the bed two times a week for deliveries but besides that that’s all
